This datasheet also covers the IR1150IS variant, as both devices belong to the same upfc one cycle control pfc ic family and are provided as variant models within a single manufacturer datasheet.
General Description
The µPFC IR1150 is a power factor correction (PFC) control IC designed to operate in continuous conduction mode (CCM) over a wide range input line voltages.
The IR1150 is based on IR's proprietary "One Cycle Control" (OCC) technique providing a cost effective solution for PFC.
Key Features
PFC with IR proprietary “One Cycle Control” Continuous conduction mode (CCM) boost type PFC No line voltage sense required Programmable switching frequency (50kHz-200kHz) Programmable output overvoltage protection Brownout and output undervoltage protection Cycle-by-cycle peak current limit Soft start User initiated micropower “Sleep Mode”.
Note: The manufacturer provides a single datasheet file (IR1150IS_InternationalRectifier.pdf) that lists specifications for multiple related part numbers.
