詳細說明
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. The proprietary control method allows major reductions in component count, PCB area and design time while delivering the same high system performance as traditional solutions. The IC is fully protected and eliminates the often noise sensitive line voltage sensing requirements of existing solutions.
主要特徵
- 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”
- Open loop protection
- Maximum duty cycle limit of 98%
- User programmable fixed frequency operation
- Min. off time of 150-350ns over freq range
- VCCunder voltage lockout
- Internally clamped 13V gate drive
- Fast 1.5A peak gate drive
- Micropower startup (<200 µA)
- Latch immunity and ESD protection
- Parts also available Lead-Free
