TLOW = 0 C; THIGH = +70C. 4. Low duty cycle pulse techniques are used during test to maintain junction temperature as close to ambient temperature as possible. 5. If the output switch is driven into hard saturation (non-Darlington configuration) at low switch currents ( 300 mA) and high driver currents ( 30 mA), it may take up to 2.0 s for it to come out of saturation. This condition will shorten the off time at frequencies 30 kHz, and is magnified at high temperatures. This condition does not occur with a Darlington configuration, since the output switch cannot saturate. If a non-Darlington configuration is used, the following output drive condition is recommended: Forced of output current switch IC OUTPUT / (IC DRIVER - 7.0 mA* ) 10 * The 100 resistor in the emitter of the driver device requires about 7.0 mA before the output switch conducts. 3 DC-to-DC CONVERTER CONTROLLER * MIK34063A DESIGN FORMULA TABLE March 2003 CALCULATION STEP-UP STEP-DOWN VOLTAGE-INVERTING tON U tOFF VOUT + VF -- VIN(MIN) VIN(MIN) -- VSAT 1 fMIN 4.0 x 10-5 tON 2 IOUT(MAX) VOUT + VF VIN(MIN) -- VSAT -- VOUT 1 fMIN 4.0 x 10-5 tON 2 IOUT(MAX) 0.3 U I PK(SWITCH) VOUT + VF VIN -- VSAT 1 fMIN 4.0 x 10-5 tON 2 IOUT(MAX) http://www.mikron.ru * (tON + tOFF)MAX CT I PK(SWITCH) MIKRON JSC * () ) tON(MAX) tON tOFF + 1 () ) tON(MAX) tON tOFF + 1 RSC L(MIN) 0.3 U I PK(SWITCH) 0.3 U I PK(SWITCH) tON(MAX) ( (VIN(MIN) -- VSAT) I PK(SWITCH) ( (VIN(MIN) -- VSAT -- VOUT) I PK(SWITCH) ) ( (VIN(MIN) -- VSAT) I 9 PK(SWITCH) CO TERMS and DEFINITIONS 9 IOUT tON VRIPPLE(PP) IPK(SWITCH) (tON + tOFF) 8 VRIPPLE(PP) IOUT tON VRIPPLE(PP) VSAT = saturation voltage of the output switch.

In practice, the calculated capacitor value will need to be increased due to its equivalent series resistance and board layout. The ripple voltage should be kept to a low value since it will directly affect the line and load regulation.
