Overview

Description

The ISL8126 dual/n-phase buck PWM controller with integrated drivers integrates two voltage-mode synchronous buck PWM controllers. It can be used either for dual independent outputs or a 2-phase single-output regulator. The ISL8126EVAL1Z evaluation board is used for a performance demo of the 2-phase single-output application.

Features

  • Input voltage (VIN): 10V to 16V
  • Output voltage (VOUT): 1.18V to 1.22V
  • Rated current: 50A
  • Switching frequency: 350kHz
  • VOUT peak-to-peak ripple: 16mVP-P

Applications

Applications

  • Power supply for datacom/telecom and POL
  • Paralleling power module
  • Wide and narrow input voltage range buck regulators

ISL8126 Dual/n-Phase Buck PWM Controller

The ISL8126 integrates two voltage-mode PWM leading-edge modulation control with input feed-forward synchronous buck PWM controllers to control dual independent voltage regulators or a 2-phase single output regulator.

Hello, I am Pengju Kong. I'm now in APEC 2012 to demo our Intersil product ISL8126.

Here we have two evaluation boards: one for 12V input and 2 output. One is 3.3V and the other is 1.2V. And we have another evaluation board for the two-phase and one output. The input of this IC can be up to 26.5V and the output can be 26V, 1.2V, 5 volt, 12V, or even higher.
