MC34063ECN ST DC-DC Converters

The MC34063ECN is a DC-DC converter control circuit from STMicroelectronics in DIP-8 through-hole package, supporting step-down, step-up, and voltage-inverting topologies. For selection, verify input from 3V to 40V, output switch current exceeding 1.5A, frequency operation up to 100kHz, low quiescent current of 2.5mA typical, 2% reference accuracy, and operating temperature from 0°C to +70°C. Features include active current limiting, internal temperature-compensated reference, comparator, duty cycle controlled oscillator, driver, and high current output switch. Ideal for battery chargers, LED drivers, negative voltage generators, distributed power systems, and any cost-effective DC-DC conversion requiring minimal external components.
