3 Description

The TLV62568A, TLV62569A 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 2 A. At the whole

load range, the device operates in pulse width

modulation (PWM) mode with 1.5-MHz switching

frequency. In shutdown, the current consumption is

reduced to less than 2 μA.

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 SOT563

package.
