APW8868B - DDR2 AND DDR3/DDR3L SYNCHRONOUS BUCK CONTROLLER

Datasheet Summary

Description

The APW8868B integrates a synchronous buck PWM controller to generate VDDQ, a sourcing and sinking LDO linear regulator to generate VTT.

It offers the lowest total solution cost in system where space is at a premium.

Features

  • Buck Controller (VDDQ).
  • High Input Voltages Range from 3V to 28V Input Power.
  • Provide Adjustable Output Voltage from 0.675V to 5.5V +1% Accuracy over Temperature.
  • Integrated MOSFET Drivers and Bootstrap Forward P-CH MOSFET.
  • Low Quiescent Current (200µA).
  • Excellent Line and Load Transient Responses.
  • PFM Mode for Increased Light Load Efficiency.
  • Constant On-Time Controller Scheme - Switching Frequency Compensation for PWM Mode - Adjust.
