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
