Datasheet Details

Part number:

ISL78220

Manufacturer:

Renesas ↗

File Size:

1.22 MB

Description:

6-Phase Interleaved Boost PWM Controller

Features

* Peak current mode PWM control with adjustable slope compensation
* Precision resistor/DCR current sensing
* 2-, 3-, 4- or 6-phase operation
* Adjustable phase dropping/diode emulation/pulse skipping for high efficiency at light load
* Phase dropping facilita

Applications

* where high efficiency (>95%) and high power are required. The multiphase boost converter architecture uses interleaved timing to multiply channel ripple frequency and reduce input and output ripple. Lower ripple results in fewer input/output capacitors and therefore lower component cost and smaller
