1.5A,Step-Up/Down Inverting Switching Regulators

DESCRIPTION

The AV34063 is a monolithic control circuit containing the

primary functions required for DC-to-DC converters. This device

consists of an internal temperature compensated reference,

comparator, controlled duty cycle oscillator with an active current

DIP-8

limit circuit,driver and high current output switch. This device was

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

and Voltage-inverting applications with a minimum number of

external components.
