MC34063AD Description

Short technical summary and product information.

The MC34063A Series from Texas Instruments is a monolithic control circuit designed for DC-to-DC converters. This series includes an internal temperature-compensated reference, comparator, controlled duty cycle oscillator with active current limit, driver, and a high-current output switch. It is specifically designed for step-down, step-up, and voltage-inverting applications, requiring a minimum number of external components.

 

Key electrical specifications include an operating input voltage range of 3.0 V to 40 V and an output switch current capability of up to 1.5 A. The device features a precision 2% reference voltage and can operate at frequencies up to 100 kHz. The maximum collector voltage for the switch and driver is 40 V.

 

This regulator is available in multiple package types, including SOIC-8, PDIP-8, and DFN8, supporting various mounting requirements. The operating ambient temperature range for the MC34063A and SC34063A is 0°C to 70°C, with a maximum operating junction temperature of +150°C.

 

The MC34063AD is suitable for a wide range of power management applications where efficient voltage conversion is required. Its robust design and broad operating parameters make it a reliable choice for embedded systems and power supply designs.
