General Description

The TD1660 is a high frequency step-down switching

regulator with integrated internal highside high voltage

power MOSFET. It provides 2A output with current mode

control for fast loop response and easy compensation.

The wide 9V to 60V input range accommodates a variety of

step-down applications, including those in automotive input

environment. A 1μA shutdown mode supply current allows

use in battery-powered applications.

High power conversion efficiency over a wide load range is

achieved by scaling down the switching frequency at light

load condition to reduce the switching and gate driving

losses.

The frequency foldback helps prevent inductor current

runaway during startup and thermal shutdown provides

reliable, fault tolerant operation.

The TD1660 is available in ESOP8 package.
