ISL6219 Datasheet PDF – Voltage Mode PWM Controller

Posted on by pinout

Part Number: ISL6219

Function: Microprocessor CORE Voltage Regulator Precision Multi-Phase BUCK PWM Controller

Package: SSOP 28 Pin Type

Manufacturer: Intersil

Image and Pinouts:

ISL6219 datasheet

 

Description

The ISL6219, ISL6219A provides core-voltage regulation by driving up to three interleaved synchronous-rectified buck-converter channels in parallel. Intersil multi-phase controllers together with ISL6207 gate drivers form the basis for the most reliable power-supply solutions available to power the latest industry-leading microprocessors. Multi-phase buck-converter architecture uses interleaved timing to multiply ripple frequency and reduce input and output ripple currents.

Features

1. Multi-Phase Power Conversion

2. Active Channel Current Balancing

3. Lossless current sense scheme

(1) Uses MOSFET’s RDS(ON)

(2) Optional current sense method higher precision

4. Precision CORE Voltage Regulation

5. Programmable Droop Voltage

6. Fast Transient Recovery Time
