The UTC UD05206 is a high-frequency, synchronous, rectified,

step-down, switch-mode converter with internal power MOSFETs.

It offers a very compact solution to achieve a 2A continuous

output current over from 2.5V to 5.5V input supply range, with

excellent load and line regulation.

The output voltage is adjustable from 0.6V to the input voltage.

During shutdown, the input is disconnected from the output and the

shutdown current is less than 1

μA. Other key features include

over-temperature and short circuit protection, and under-voltage

lockout to prevent deep battery discharge.

The UTC UD05206 at 2A maximum output current. Ultra-low

the UTC UD05206 an ideal choice for high-output voltage,

high-current applications which require a low dropout threshold.
