Part Number: TPS62742
The basic requirements of the chip: low Iq, high efficiency at light load, maximum output current 0.4A, input voltage is 3V~5.5V, the highest possible duty cycle (100% best).
The problem with TPS62742 is that when Vout ≤ Vin ≤ Vout + 0.7, Iout + Iload is 100 mA.
Help recommend a similar TPS62742, the output current is 400mA when the input voltage is under any condition.
