TPS6755 Datasheet (Texas Instruments) - ADJUSTABLE INVERTING DC/DC CONVERTER

TPS6755, ADJUSTABLE INVERTING DC/DC CONVERTER

The TPS6755 is an adjustable inverting dc/dc converter capable of operating from inputs as low as 2.7 V.

The only external components required are an inductor, an output filter capacitor, an input filter capacitor, a reference filter capacitor, two resistors, and a Schottky rectifier.

TPS6755 Features

* a 160-kHz current-mode pulse-width-modulation (PWM) controller with a p-channel MOSFET power switch. The gate drive uses the converter output to reduce the die area needed to realize the 0.4-Ω MOSFET. Soft start is accomplished with the addition of one small capacitor at SS. A 1.22-V reference is av
