DC TO DC CONVERTER CONTROLLER

DESCRIPTION

The TD34063 Series is a monolithic control circuit containing the

primary functions required for DC to DC converters. These devices

consist of an internal temperature compensated reference, comparator

controlled duty cycle oscillator with an active current limit circuit,

driver and high current output switch. This series was specifically

designed to be incorporated in Step-Down and Step-Up and

Voltage-Inverting applications with a minimum number of external

components.

SOP-8

FEATURES

*Operation from 3.0V to 40V.

*Short circuit current limiting.

*Low standby current.

*Output switch current of 1.5A without external

transistors.

DIP-8

*Frequency of operation from 100Hz to 100kHz.

*Step-up, step-down or inverting switch regulators.
