SOT-23 Boost PFC Control IC

Features

Description

The IRS2505 is a control IC for boost-type

PFC circuits operating in critical-conduction

•

Critical-conduction mode PFC control

High PF and ultra-low THD

Wide load and line range

Regulated and programmable DC bus voltage

No secondary winding required

MOSFET cycle-by-cycle over-current protection

DC bus over-voltage protection

Low EMI gate drive

•

mode. The IC incorporates

free-running

frequency oscillator with on- and off-time control

of the boost power MOSFET without the need for

a secondary winding. Also included in the design

is over-voltage protection of the DC bus and

cycle-by-cycle over-current protection of the

power MOSFET. Micro-power start-up current and

an internal 20.8V zener clamp at VCC are

provided to simplify the external VCC supply

circuitry. ESD and latch immune CMOS

technology enables a rugged monolithic IC

construction.

Ultra-low start-up current

20.8V internal zener clamp on VCC

Excellent ESD and latch immunity

RoHS compliant
