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%
TI Information – Selective Disclosure
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%
