3 Description

The TPS62A01x-Q1 family of devices are

synchronous step-down buck DC-DC converters

optimized for high efficiency and compact design size.

The devices integrate switches capable of delivering

an output current up to 1 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 TPS62A01A-Q1

variants of this device family operate in forced PWM

across the whole load current range.

The TPS62A01x-Q1 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.
