1.5A STEP-DOWN/STEP-UP/INVERTING DC-DC CONVERTER
General Description
Features
AZ34063A
The AZ34063A is a monolithic switching regulator
control circuit containing the primary functions
required for DC-DC converters. This device consists
of internal temperature compensated reference, voltage
comparator, controlled duty cycle oscillator with active
current limit circuit, driver and high current output
switch. This device was specifically designed to be
used in Step-Down, Step-Up and Voltage-Inverting
applications with a minimum number of external com-
ponents.
