IR1153S

FIXED 22.2kHz FREQUENCY, µPFC ONE CYCLE CONTROL

IC WITH BROWN-OUT PROTECTION

Features

Description Package

? PFC IC with IR proprietary “One Cycle Control” ? Continuous conduction mode boost type PFC ? Fixed 22.2kHz switching frequency ? Average current mode control ? Input line sensed brownout protection ? Output overvoltage protection ? Open loop protection ? Cycle by cycle peak current limit

? VCC under voltage lockout ? Programmable soft start ? Micropower startup ? User initiated micropower “Sleep Mode” ? 750mA peak gate drive

? Latch immunity and ESD protection The μPFC IR1153 power factor correction IC, based on IR proprietary

"One Cycle Control" (OCC) technique, provides for high PF, low THD and excellent DC Bus regulation while enabling drastic reduction in

component count, PCB area and design time as compared to traditional solutions. The IC is designed to operate in continuous conduction mode Boost PFC converters with average current mode control at a fixed 22.2kHz switching frequency. The IR1153 features include input-line sensed brown-out protection, dedicated pin for over voltage protection, cycle by cycle peak current limit, open loop protection, VCC UVLO, soft-start and micropower startup current of less than 75µA. In addition, for standby power requirements, the IC can be driven into a micropower sleep mode by pulling the OVP/EN pin low where the current consumption is less than 75uA. IR1153 is available in SO-8 package.

Absolute Maximum Ratings

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these conditions is not implied. All voltages are absolute voltages referenced to COM. Thermal resistance and power dissipation are measured under board mounted and still air conditions.

Electrical Characteristics

The electrical characteristics involve the spread of values guaranteed within the specified supply voltage and junction temperature range T J from – 25° C to 125°C. Typical values represent the median values, which are related to 25°C. If not otherwise stated, a supply voltage of V CC =15V is assumed for test condition.
