Overview

CM1821hf is a 300mA, synchronous step-down integrated buck DC-DC converter IP core optimized for 3MHz fixed frequency operation and designed for CV018MS (0.18um HV).

The input voltage is fixed in 5V and the output voltage can be configured to 1.2V or 1.8V. It operates in PWM (current control mode) for heavy loads and has a PFM mode for light loads, improving it’s efficiency.

It also features integrated compensation and rectifier switches, power good indicator and over-current protection (at start-up and cycle-bycycle).

Key features

  • 5V Input Voltage
  • 1.2/1.8V Output Voltage options
  • 300mA maximum current load
  • Optimized for 3MHz fixed frequency operation
  • Internal synchronous rectifier and compensation
  • PWM current control mode for heavy loads
  • PFM control for light loads
  • Power good indicator
  • Over-current protection
  • Fast and controlled start-up
  • Area: 0.85 mm2(x=1304 um, y=652 um)
