Description

The TPP36106x series is a simple, easy-to-use, 1-

A output, synchronous, step-down, and switch-mode

converter with internal power MOSFETs.

The TPP36106x integrates low-RDS(ON) power transistors

in the TSOT23-6 package with internal soft-start,

compensation, and protection features. The TPP36106x

offers a very compact solution to achieve a 1-A continuous

output current over a wide input supply range, with

excellent load and line regulation.

The TPP36106 has different versions of switching

frequency at 500-kHz, 1-MHz, and 2.2-MHz, and also

supports light load PSM to save quiescent current and

forced-PWM mode to maintain fixed switching frequency.

The device is available in the 6-pin TSOT23-6 package

with the support of a wide operation ambient temperature

range from ?40 °C to 125 °C.
