TPS62740 - Texas Instruments

TPS62740 Step Down Converter

The TPS6274x is industry's first step down converter featuring typ. 360nA quiescent current and operating with a tiny 2.2µH inductor and 10µF output capacitor. This new DCS-Control™ based device extends the light load efficiency range below 10µA load currents. TPS62740 supports output currents up to 300mA, TPS62742 up to 400mA. The device operates from recha.
