Power Factor Correction Controllers

ISL6730A, ISL6730B, ISL6730C, ISL6730D

The ISL6730A, ISL6730B, ISL6730C, ISL6730D are active

power factor correction (PFC) controller ICs that use a boost

topology. (ISL6730B, ISL6730C, ISL6730D are Coming Soon.)

The controllers are suitable for AC/DC power systems, up to

2kW and over the universal line input.

The ISL6730A, ISL6730B, ISL6730C, ISL6730D are operated

in continuous current mode. Accurate input current shaping is

achieved with a current error amplifier. A patent pending

breakthrough negative capacitance technology minimizes zero

crossing distortion and reduces the magnetic components

size. The small external components result in a low cost design

without sacrificing performance.

The internally clamped 12.5V gate driver delivers 1.5A peak

current to the external power MOSFET. The ISL6730A,

ISL6730B, ISL6730C, ISL6730D provide a highly reliable

system that is fully protected. Protection features include

cycle-by-cycle overcurrent, over power limit, over-temperature,

input brownout, output overvoltage and undervoltage

protection.

The ISL6730A, ISL6730B provide excellent power efficiency

and transitions into a power saving skip mode during light load

conditions, thus improving efficiency automatically. The

ISL6730A, ISL6730B, ISL6730C, ISL6730D can be shut down

by pulling the FB pin below 0.5V or grounding the BO pin. The

ISL6730C, ISL6730D have no skip mode.

Two switching frequency options are provided. The ISL6730B,

ISL6730D switch at 62kHz, and the ISL6730A, ISL6730C

switch at 124kHz.
