AZ34063UP-G1

AZ34063U 1.5A STEP-DOWN/STEP-UP/INVERTING DC-DC CONVERTER Description Pin Assignments The AZ34063U is a monolithic, switching regulator, control circuit which contains the primary functions required for DC-DC converters. This device consists of an internal temperature compensated reference, voltage comparator, controlled duty-cycle oscillator with active current-limit circuit, driver, and high-current output switch. The AZ34063U 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.
