TPS6735IDR

TEXAS INSTRUMENTS  TPS6735IDR.  芯片, 直流/直流转换器, -5V, 200mA

description

The TPS6735 is a fixed negative 5-V output inverting dc/dc converter capable of delivering 200 mA from inputs as low as 4.5 V. The only external components required are an inductor, an output filter capacitor, an input filter capacitor, a reference filter capacitor, and a Schottky rectifier. An enable input is provided to shut down the inverter when a –5-V output is not needed. The typical supply current is 1.9 mA at no-load and is further reduced to 1-µA when the enable input is low.
