General Description

The TPMP1470 is a fully integrated, high-

efficiency 2.0A synchronous rectified

step-down converter. The TPMP1470 operates

at high efficiency over a wide output current

load range.

This device offers two operation modes,

PWM control and PFM Mode switching

control, which allows a high efficiency over

the wider range of the load.

The TPMP1470 requires a minimum number of

readily available standard external

components and is available in a 6-pin

SOT23 ROHS compliant package.
