ICE3PCS01G PFC-CCM Controller IC The ICE3PCS01G is a 14-pin wide input range controller IC for active power factor correction converters. It is designed for converters in power boost topologies that require high efficiency and power factors, such as PCs, servers, LCD/PDP TVs and telecom. The gate switching frequency is adjustable from 21kHz to 100kHz and able to synchronize with external switching frequency from 50kHz to 100kHz. Voltage loop compensation is digitally integrated for better dynamic response and less design effort. It is a spare part of the controller IC for repairing the hash board.

Features:

High efficiency over the whole load range

Accurate and adjustable switching frequency

Bulk voltage good signal for inrush relay control or PWM IC enabling

Fast output dynamic response during load jump without input current distortion

External synchronization

Extra-low peak current limitation

Continuous current operation mode PFC

The wide input range of Vcc up to 25V

Programmable boost follower step level according to input line and output power conditions

Accurate brown-out protection threshold

External current loop compensation for greater user flexibility

Open-loop protection, second over bulk voltage protection

Separate signal and power ground pins

The maximum duty cycle of 95% (typical)

Applications:

Hash board chip repair
