IRS2505LPBF Datasheet Sot-23 Boost Pfc Controller

Manufacturer: International Rectifier (now Infineon)

Overview: IRS2505LPBF µPFCTM.

General Description

The IRS2505 is a control IC for boost-type PFC circuits operating in critical-conduction mode.

The IC incorporates a 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.

Key Features

  • 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 Ultra-low start-up current 20.8V internal zener clamp on VCC Excellent ESD and latch immunity RoHS compliant 5-pin.
