BL8851
BL8851 is Current Mode PWM Power Switch manufactured by BELLING.
Current Mode PWM Power Switch
GENERAL DESCRIPTION
BL8851 bines a dedicated current mode PWM controller. It is optimized for high performance, low standby power, and cost effective off- line flyback converter applications in 40W~60W range. BL8851 offers plete protection coverage with automatic self-recovery feature including Cycle- by-Cycle current limiting (OCP),CS short protection, CS floating protection, over load protection (OLP), and VDD under voltage lockout (UVLO), over temperature protection (OTP), over voltage(fixed or adjustable) protection (OVP). The tone energy at below 20KHZ is minimized in the design and audio noise is eliminated during operation.. BL8851 is offered in SOT23-6 package.
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
- Audio Noise Free Operation
- Fixed 65KHZ Switching Frequency
- Internal Synchronized...
