3 Description

The TPS62A01 family of devices are synchronous

step-down buck DC-DC converters optimized for high

efficiency and compact solution size. The device

integrates switches capable of delivering an output

current up to 1 A. At medium to heavy loads, the

device operates in pulse width modulation (PWM)

mode with 2.4-MHz switching frequency. At light load,

the device automatically enters power save mode

(PSM) to maintain high efficiency over the entire load

current range. In shutdown, the current consumption

is minimal as well. The TPS62A01A variants of this

device family operate in forced PWM across the

whole load current range.

The TPS62A01 provides an adjustable output voltage

through an external resistor divider. An internal softstart

circuit limits the inrush current during start-up.

Other features like overcurrent protection, thermal

shutdown protection, and power good are built-in. The

device is available in a SOT-5X3 package.
