TPS54062

4.7V至60V的输入为50mA同步降压转换器与低智商 4.7V to 60V Input, 50mA Synchronous Step-Down Converter with Low IQ

DESCRIPON

The device is a 60V, 50-mA, synchronous step-down converter with integrated high side and low side MOSFETs. Current mode control provides simple external compensation and flexible component selection. The non switching supply current is 89µA. Using the enable pin, shutdown supply current is reduced to 1.7µA.
