AZ34063D

1A STEP-DOWN/STEP-UP/INVERTING DC-DC CONVERTER General Description Features Data Sheet AZ34063D The AZ34063D 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 AZ34063D 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 AZ34063D 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 to1A Output Voltage Adjustable Operation Frequency up to 180kHz (CT=100pF) Precision 2% Reference Applications · Battery Chargers · ADSL Modems · Hubs · Negative Voltage Power Supplies SOIC-8 DIP-8 Figure 1.
