Introduction

AI Translation

The TPS62743 is a high-efficiency step-down converter with an ultra-low quiescent current of typically 360nA. The device is optimized to operate with a 2.2μH inductor and 10μF output capacitor. It employs DCS-Control™ technology with a typical switching frequency of 1.2MHz. In power-save mode, the device extends light-load efficiency down to 10μA load current and below. The TPS62743 delivers 300mA output current. After startup, the device operates at input voltages as low as 2.0V, enabling direct operation from a single Li-MnO₂ coin cell battery.

The TPS62743 offers 8 programmable output voltages selectable from 1.2V to 3.3V via three selection pins. The TPS62743 is optimized to achieve low output voltage ripple and low noise using only a small output capacitor. When the input voltage approaches the output voltage, the device enters a ripple-free 100% duty cycle mode to prevent increased output ripple voltage. In this operating mode, the device halts switching and turns on the high-side MOSFET switch.
