?PFC Power Factor Correction (PFC) ICs
PRESS RELEASE
DATA SHEET
The IR115x ICs, utilizing IRs One Cycle Control
(OCC) technology, offer high power factor (PF),
low total harmonic distortion (THD) and excellent
DC bus regulation while enabling drastic
reduction in component count, PCB area and design
time compared to traditional solutions. The ICs
are designed to operate in continuous conduction
mode Boost PFC converters with average current
mode control over 85-264 VAC input line voltage
range.

• Features
• Low cost, 8-pin PFC IC with high-level of system
  protections, minimizes system design steps
• Continuous conduction mode lowers peak current
  and reduces conduction loss
• Average current mode results in better THD
• Dedicated 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
• Brown-out protection (IR1152/IR1153)

• Advantages
• The new ?PFC ICs offer advanced system-enabling
  and protective features including dedicated pin
  for over-voltage protection, cycle by cycle peak
  current limitation, open loop protection, VCC
  UVLO and programmable soft-start.
• The user initiated micropower startup/sleep-mode
  enables compliance with standby power
  requirements mandated by regulations such as
  Energy Star, Green Power and Blue Angel.
• The IR1155S offers programmable switching
  frequency between 48 kHz to 200 kHz based on the
  specific application requirement.
• The IR1152S and IR1153S offer fixed switching
  frequency of 66 kHz and 22.2 kHz respectively.
  These devices are compatible with IRs Ultrafast
  and Warp IGBTs for systems with power ratings
  higher than 750 Watt and switching frequency up
  to 100 kHz.
