MC33063ADR – 1.5A Buck/Boost/Inverting Switching Regulator IC

The MC33063ADR is a versatile and easy-to-use DC-DC switching regulator IC designed for buck, boost, and inverting converter topologies. This all-in-one power management solution integrates the primary components required for DC-DC conversion, including a temperature-compensated reference, comparator, oscillator, PWM controller with active current limiting, and a high-current output switch capable of driving up to 1.5A. With minimal external components, the MC33063ADR enables designers to build compact, efficient, and reliable power supply circuits.

Operating over a wide input voltage range of 3V to 40V, this IC is suitable for automotive, industrial, and battery-powered systems. The precision 2% internal reference ensures stable output voltage regulation, while the active current limiting and short-circuit protection enhance circuit safety and reliability. The internal oscillator can be adjusted up to 100kHz, allowing flexibility in selecting external components for the desired output performance. The device’s low standby current further improves system efficiency in power-sensitive designs.

Key Features

  • Wide Input Voltage Range: Operates from 3V to 40V for broad compatibility with various power sources.
  • High Output Switch Current: Supports up to 1.5A continuous current for efficient power delivery.
  • Adjustable Output Voltage: Easily configurable for step-up (boost), step-down (buck), or inverting converter designs.
  • Integrated Oscillator: Frequency adjustable up to 100kHz for optimized performance.
  • Precision Voltage Reference: +-2% internal reference ensures stable output voltage.
  • Active Current Limiting: Protects against overcurrent and short-circuit conditions.
  • Low Standby Current: Enhances efficiency in low-power and standby modes.
  • Built-In PWM Controller: Provides efficient and stable switching operation.
  • Temperature Range: Operates reliably from –40 C to+85 C for industrial environments.
  • Compact SOIC-8 Package: Simplifies PCB layout and offers robust thermal characteristics.
