MIC33M656 Datasheet Power Module Buck Converter

Manufacturer: Microchip Technology

Overview: MIC33M656 6A, Power Module Buck Converter with HyperLight Load® and I2C.

General Description

The Microchip MIC33M656 is an I2C programmable, high-efficiency, low-voltage input, 6A current, synchronous step-down regulator power module with integrated inductor.

The Constant-On-Time (COT) control architecture with HyperLight Load® mode provides very high efficiency at light loads, while still having ultra-fast transient response.

The I2C interface allows programming the output voltage, between 0.6V and 1.28V with 5 mV resolution, or between 0.6V and 3.84V with 10 mV and 20 mV resolution.

Key Features

  • Input Voltage Range: 2.4V to 5.5V.
  • 6A Output Current.
  • Multiple Faults Indication through I2C.
  • I2C Programmable: - Output voltage: 0.6V-1.28V, 5 mV resolution; 0.6V-3.84V, 10/20 mV resolution - Slew rate: 0.2 ms/V-3.2 ms/V - On time (switching frequency) - High-side current limit: 3.5A-10A - Enable delay: 0.2 ms-3 ms - Output discharge when disabled (EN = GND).
  • High Efficiency (up to 95%).
  • Ultra-Fast Transient Response.
  • ±1.5% Output.
