FAN5236 - Dual Mobile-Friendly DDR / Dual-Output PWM Controller

General Description

The FAN5236 PWM controller provides high ef f iciency and regulation for tw o output voltages adjustable in the range of 0.9V to 5.5V required to pow er I/O, chip-sets, and memory banks in high-performance notebook computers, PDAs, and Internet appliances.

Key Features

  • Highly Flexible, Dual Synchronous Sw itching PWM Controller that Includes Modes for: - DDR Mode w ith In-phase Operation for Reduced Channel Interference - 90° Phase-shifted, Tw o-stage DDR Mode for Reduced Input Ripple - Dual Independent Regulators, 180° Phase Shifted.
  • Complete DDR Memory Pow er Solution - VTT Tracks VDDQ/2 - VDDQ/2 Buffered Reference Output.
  • Lossless Current Sensing on Low -side MOSFET or Precision Over-Current Using Sense Resistor.
  • VCC Under-Voltage Locko.
