MC34063 is a monolithic control circuit from Motorola (MOT.

The MC34063 is a monolithic control circuit from Motorola (MOT.ST) that contains the primary functions required for DC-DC converters.

Specifications:

  • Input Voltage Range: 3V to 40V
  • Output Current: Up to 1.5A (switch current)
  • Switching Frequency: Up to 100kHz
  • Duty Cycle Adjustable: Up to 100%
  • Low Standby Current: Typically 2.5mA
  • Operating Temperature Range: 0°C to +70°C (commercial), -40°C to +85°C (industrial)

Descriptions:

The MC34063 integrates a temperature-compensated reference, comparator, controlled duty cycle oscillator, driver, and high-current output switch. It is designed for step-up (boost), step-down (buck), and voltage-inverting (buck-boost) applications.

Features:

  • Versatile: Can be used in boost, buck, and inverting configurations
  • Low Cost: Simple external components required
  • Short-Circuit Protection: Built-in current limiting
  • Adjustable Output Voltage: Via external resistors
  • Efficient: Suitable for battery-powered applications

This information is based on the manufacturer's datasheet for the MC34063 from MOT.ST (Motorola).
