3 Description

The TLV62569 device is a synchronous step-down

buck DC-DC converter optimized for high efficiency

and compact solution size. The device integrates

switches capable of delivering an output current up to

2 A.

At medium to heavy loads, the device operates in

pulse width modulation (PWM) mode with 1.5-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

reduced to less than 2 μA.

The TLV62569 provides an adjustable output voltage

via an external resistor divider. An internal soft start

circuit limits the inrush current during startup. Other

features like over current protection, thermal

shutdown protection and power good are built-in. The

device is available in a SOT23 and SOT563 package.
