BCS Flyback Exmple

30~800Vin 21Vo/1.5A


How to Calculate Boost Output Current?

Iout = (ILIM * Vin / Vout) * ŋ

ILIM = 1.7A MIN

Condition: Vin = 1V, Vout = 3V, Iout = 0.5A, ŋ = 90%


How to Calculate the Boost Iq Roughly?

Total IQ = IQin + (IQout *Vout/Vin)/ŋ

Total IQ = 0.4 + (0.6 * 3/1.5)/89% = 1.8uA

Condition: Vin = 1.5V, Vout = 3V, Iout = 10mA ŋ = 89%
