Caution note for operation (1) Output voltage establishment range is changed by input voltage.Please refer to the Fig.8. (2) Layout of external parts may significantly change the output spike noise or characteristics or cause abnomal oscillation and temperature increase. Note the following for layout. * Provide the input smoothing electroytic capacitor close to the FET source and pin 2 of the module. * Provide the output smoothing electrolytic capacitor close to pin 6 of the module together with the current detection resistor * Large current may run into the coil, current detection resistor and output through the FET sourcedrain.Try to use a solid pattern as much as possible. * FET drain, coil and flywheel diode may generate heat by power loss. Try to use a solid pattern so that the heat may be released. Measure a rise in temperature of each element and make sure that it is not abnormal. * Provide the negative terminal of the I/O smoothing capacitor and anode terminal of the flywheel diode close to GND pin 4 of the module. * Connect the negative terminal of the I/O smoothing electrolytic capacitor and anode terminal of the flywheel diode nearby. (3) Output load may cause large ripple current in the I/O smoothing electrolytic capacitor. Note the allowable ripple current of the capacitor to be used. (4) As the output smoothing electrolytic capacitor, one with especially low impedance is recommended for suppresing output ripple voltage. Select a capacitor suited for the use. (5) Please be sure to use protection circuit function.(R1 should not be 0.) Output voltage establishment and application circuit example

(2) FET(Q1) FET is determined by taking the peak current flowed to the external FET, drain-source voltage(VDS), ON resistance(RDS(ON)), input capacity(Ciss), allowable loss of package, and area of safe operation. For the basic circuit example(Fig.9), FET of 2SJ529S/Hitachi is used. Please use FET with the characteristic equal to or than this one.Especially, the input capacity(Ciss), and ON resistance may cause a larger FET loss. Note the FET with the characteristic equal to or higher to be used. The characteristic of 2SJ529S is VDS =-60V ID =-10A RDS(ON) =0.17TYP(ID=-5A, VDS=-4V) Pch =20W(Tc=25C) Ciss =580PF (3) Inductor(L1) inductor L1 is determined by the following expression in consideration of output ripple current. L1n x (Vi-Vo)/Io x 1/f x Vo/Vi [H] Vi : Input voltage [V] Vo : Output voltage [V] Io : Output current [A] f : Oscillation frequency (190KHz) n : Ripple current condition Io/n is ripple current. Normally, n=2.55 is recommended. L is determined from above. Peak current flowed into the inductor by the determined L is ip=Io+(Vi-Vo)/2 x 1/L1 x 1/f x (1-Vo/Vi) [A] ip for actual usage is calculated back by the L of the expression above. Ripple current ir by the determined L is ir=(Vi-Vo)/L1 x 1/f x Vo/Vi [A] As stated above, after L1[H] inductor and the ip[A] peak current are determined, an inductor for these specifications can be determined. Output ripple voltage is determined by the multiplication of the ir[A] ripple current and the impedance of the smoothing capacitor. Vr=ir x Zc Vr : Output ripple voltage [Vp-p] Zc: Impedance of smoothing capacitor[]
