3 Description

The TPS62A0x family of devices are synchronous

step-down buck DC-DC converters optimized for high

efficiency and compact solution size. The devices

integrate switches capable of delivering an output

current up to 2 A. At medium to heavy loads, the

devices operate in pulse width modulation (PWM)

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

the devices automatically enter power save mode

(PSM) to maintain high efficiency over the entire load

current range. In shutdown, the current consumption

is minimal as well. The TPS62A0xA variants of this

device family operate in forced PWM across the

whole load current range.

The TPS62A0x devices provide an adjustable output

voltage through an external resistor divider. An

internal soft-start circuit limits the inrush current during

start-up. Other features like overcurrent protection,

thermal shutdown protection, and power good are

built-in. The devices are available in a SOT-563

package.
