Data Sheet
AZ34063C
The AZ34063C is a monolithic switching regulator
control circuit which contains 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.
The AZ34063C is specifically designed as a general
DC-DC converter to be used in Step-Down, Step-Up
and Voltage-Inverting applications with a minimum
number of external components.
The AZ34063C is available in 2 packages: SOIC-8 and
DIP-8.
• Operation from 3.0V to 36V Input
• Low Standby Current
• Current Limiting
• Output Switch Current to 0.8A
