Overview
OBSOLETE – PART DISCONTINUED PART OBSOLETE – CONTACT US AZ34063C 1A STEP-DOWN/STEP-UP INVERTING DC-DC CONVERTER Description 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.
Pin Assignments (Top View) 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.
Features  Operation from 3.
0V to 36V Input  Low Standby Current  Current Limiting  Output Switch Current to1A  Output Voltage Adjustable  Operation Frequency up to 180kHz (CT=100pF)  Precision 2% Reference  For automotive applications requiring specific change control (i.
