1 Introduction

The TPS6269x devices are a series of high-frequency, synchronous, step-down dc-dc converters

optimized for battery-powered portable applications. Intended for low-power applications, the TPS6269x

can support up to 600-mA load current and allows the use of low-cost chip inductors and capacitors. The

TPS62691 and TPS62690 have fixed output voltages of 2.2 V and 2.85 V respectively. The TPS6269x

operates at a regulated 4-MHz switching frequency and enters a power-save mode operation under light

load currents in order to maintain high efficiency over the entire load-current range. A PFM mode extends

the battery life by reducing the quiescent current to 19 μA (typical) during light load operation.
