MB3873 11 n functional description 1. switching regulator function (1) reference voltage circuit (ref) the reference voltage circuit takes the voltage from the vcc terminal (pin 11) and generates a temperature- compensated reference voltage ( : = 8v), which is used as the reference voltage supply for the ic internal circuit bias and detection comparator. a reference voltage can be output from the vref terminal (pin 10) at levels up to 10ma. (2) triangular-wave oscillator circuit (osc) this circuit is used to generate a triangular oscillator waveform, by connecting timing capacitor and resistor to the ct terminal (pin 2) and rt terminal (pin 1) respectively. the triangular waveform frequency fosc1 is set according to the timing capacitor and resistor. the triangular oscillator waveform is input to the ics internal dead time timing circuit (one-shot-dtc), and can be output from the ct terminal. (3) oscillator frequency control circuit (osc control) the oscillator control circuit detects the ac/dc converter output voltage and outputs the pfm control signal to the triangular wave oscillator. the fb terminal (pin 5) carries the ac/dc converter output voltage at the v/i converted osc control current. when an overload occurs, the detection signal to the overload detection circuit (ocp comp.) is also output here. (4) dead time timing circuit (one-shot-dtc) the dead time timing circuit converts the triangular waveform generated by the triangular wave oscillator to a rectangular wave having a pulse width ( = dead time t dead ) set by the dead time setup resistor that is connected to the rd terminal (pin 3). (5) output circuit (drive) the output circuit has totem pole configuration, and outputs the pfm signal from the out terminal (pin 8). the output circuit power is supplied from the vcc (o) terminal (pin 9). 2. protective function (1) undervoltage lockout circuit (uvlo) power-on surges and momentary drops in power supply voltage can cause errors in control ic operation, which can destroy or damage systems. to prevent the error operation, the uvlo comp.1 circuit detects low voltage conditions in the supply voltage (vcc), and sets the vref terminal (pin 10) to l level. the uvlo comp.2 circuit detects low voltage conditions in the reference voltage, and sets the out pin (pin 8) to l level. overvoltage/overload/over temperature conditions cause the error detection latch (latch) to be set. if the vref terminal (pin 10) is set to l level, and the supply voltage falls below the uvlo circuit threshold voltage (vthl), the uvlo comp.1 resets the error detection latch. operation is restored when the power supply voltage returns above the threshold voltage (vthl) of the uvlo circuit. the threshold voltage can be set to any desired level by connecting resistor between the enb terminal (pin 12) and gnd terminal (pin 7), or between the enb terminal (pin 12) and vcc terminal (pin 11) (for internal resistance constants see block diagram). (2) overvoltage detection comparator 1 (ovp comp. 1) when the input voltage at the ovp terminal (pin 14) is greater than the threshold voltage ( : = 2.5v), the overvoltage comparator 1 sets the error detection latch, and sets the vref terminal (pin 10) and out terminal (pin 8) to l level. note that if ovp comp.1 is not used, the ovp terminal (pin 14) should be shorted to gnd by the shortest path (see processing when ovp pin is not used).
MB3873 12 (3) overvoltage detection comparator 2 (ovp comp.2) when the input voltage at the +in terminal (pin 15) is greater than the input voltage at the -in terminal (pin 16), the cs terminal is set to l level causing the frequency to increase. when the +in input voltage falls below the -in input voltage, soft start processing is performed to restart operation. overvoltage detection comparator 2 does not provide the same latch operation as ovp comp.1. note that if ovp comp.2 is not used, the +in terminal (pin 15) should be shorted to gnd, and the -in terminal (pin 16) should be connected to the vref terminal (pin 10) by the shortest path (see processing when overvoltage detection comparator 2 is not used). (4) overload detection comparator circuit (ocp comp.) when an overload occurs, the ocp comp. circuit detects the overload signal output by the oscillator frequency control circuit, and after a given interval sets the error detection latch and sets the vref terminal (pin 10) and out terminal (pin 8) to l level. the time interval from overload detection to setting of the error latch is determined by the delay interval setting capacitor connected to the cd terminal (pin 4). note that if the overload detection function is not used, the cd terminal (pin 4) should be shorted to gnd by the shortest path (see processing when the cd pin is not used). (5) overtemperature detection comparator (otp comp.) the over temperature detection comparator detects the input voltage at the otp terminal (pin 13) and if greater than the threshold voltage ( : = 0.98v) sets the error detection latch, and sets the vref terminal (pin 10) and out terminal (pin 8) to l level. note that if the overtemperature detection function is not used, the otp terminal (pin 13) should be shorted to gnd by the shortest path (see processing when otp pin is not used). 3. soft start function soft start circuit (cs) the MB3873 oscillator frequency control circuit includes an on-chip soft start circuit. soft starting can be provided by connecting a capacitor to the cs terminal (pin 6). at start up, this causes the pfm control signal to be input to the triangular wave oscillator, thereby controlling the control frequency and preventing current rush. note that if the soft start function is not used, the cs terminal (pin 6) should be left open. (see processing when cs pin is not used.) n setting the oscillator frequency the oscillator frequency is set by the timing capacitor c t and timing resistor r t connected to the ct pin and rt pin respectively. oscillator frequency f osc (when frequency control is not exerted by the fb, cs pins) n setting the dead time the dead time is set by the dead time resistor r d connected to the rd pin. dead time (output pin square wave pulse width) t dead [ns] : = 4.8 r d [k w ] C 44 f osc [khz] : = 7.6 10 5 c t [pf] r t [k w ]
MB3873 13 n setting the soft start time when the MB3873 is started, the soft start capacitor (cs) connected to the cs terminal begins charging. while the cs terminal voltage is : = 0 to 1.1v, the oscillator frequency is controlled by the cs terminal voltage, thereby controlling the output voltage. the soft start capacitor charging current is as follows ics1 : = 25 m a (cs pin voltage : = 0 to 1.1v) ics2 : = 2.5 m a (cs pin voltage : = 1.1 to 3.1v (cs pin clamp voltage)) soft start time (time until cs pin voltage reaches 1.1v) n settng the overload detection delay time when an overload condition is detected, the delay capacitor (c d ) connected to the cd terminal starts charging ( : = 10 m a), increasing the cd terminal voltage. when the cd terminal voltage exceeds the threshold voltage ( : = 4v), the error detection latch is set, and the vref terminal (pin 10) and out terminal (pin 8) are set to l level. overload detection delay time (time from overload detection until error latch is set) t c s [s] : = 1.2 c s [ m f] 25 [ m a] t c s [s] : = 3.9 c d [ m f] 10 [ m a]
