MIC33M356 - Power Module Buck Converter

General Description

The Microchip MIC33M356 is a I2C programmable, high-efficiency, low-voltage input, 3A current, synchronous step-down regulator power module with integrated inductor.

Key Features

  • Input Voltage Range: 2.4V to 5.5V.
  • 3A Output Current.
  • Multiple Faults Indication through I2C.
  • I2C Programmable: - Output voltage: 0.6V to 1.28V at 5 mV resolution or 0.6V to 3.84V, 10 and 20 mV resolution - Slew rate: 0.2 ms/V to 3.2 ms/V - On-time (switching frequency) - High-side current limit: 3.5A or 5A - Enable delay: 0.2 ms-3 ms - Output discharge when disabled (EN = GND).
  • High Efficiency (up to 95%).
  • Ultra-Fast Transient Response.
