Description

General part information

TPS62843 Series

The TPS62843 is a high-efficiency, step-down converter family with ultra-low operating quiescent current of typically 275nA. The device features a 4nA shutdown (typical) current when disabled.

The device uses DCS-Control with a low and RF-friendly output voltage ripple to power radios.

The device operates with a typical switching frequency of 1.5MHz and extends a high efficiency at light-load down to 100µA load current and below.
