OB2283K
Description
OB2283K is a highly integrated current mode PWM control IC optimized for high performance, low standby power and cost effective offline flyback converter applications. PWM switching frequency at normal operation is internally fixed and is trimmed to tight range.
Key Features
- Power on Soft Start Reducing MOSFET Vds Stress
- Frequency shuffling for EMI
- Extended Burst Mode Control For Improved Efficiency and Minimum Standby Power Design
- Ultra Low Operating Current at Light Load (0.6mA)
- Audio Noise Free Operation
- Normal 65KHz Switching Frequency
- Frequency Triple for peak load(195Khz)
- Adjustable Overload Protection (OLP) delay time
