MC34063A Buck Boost Inverting Switching Regulators


The ON Semiconductor MC34063A series of buck boost inverting switching regulators designed for step-down, step-up and voltage-inverting applications.

These are monolithic ICs which contain a wide range of functionality required for DC-DC converters. This functionality includes:

- Internal temperature compensated reference

- Comparator

- Controlled duty cycle oscillator with an Active current limit circuit

- Driver

- High current output switch

The MC34063A ICs are suitable for fan controllers and DC-DC power supplies. They offer a wide input voltage of -0.3 to +40 Vdc, which makes the MC34063A suitable for a wider range of applications.

• Temperature range: 0 to +70 °C

• Low standby current

• Input voltage: 3-40 V

• Adjustable current limit

• Adjustable output voltage

• Frequency operation: to 100kHz

• Accuracy: precision 2% reference
