Overview
The SY5881 is a single stage Buck and PFC controller targeting at LED lighting applications with PWM or Analog dimming. It is a primary side controller without applying any secondary feedback circuit for low cost, and drives the Buck converter in the quasi-resonant mode to achieve higher efficiency. It keeps the Buck converter in constant on time operation to achieve high power factor.
Applications
- LED lighting
Key features
- High dimming accuracy
- Dimming Range from 5.5% to 100.0%
- CV mode for Bias supply at <2.5% Dimming Signal
- Valley turn-on of the primary MOSFET to achieve low switching losses
- 300mV primary current sense reference voltage leads to a lower sense resistance thus a lower conduction loss
- Internal high current MOSFET driver: 200mA sourcing and 650mA sinking
- Low start up current: 34μA typical
- Reliable short LED and Open LED protection
- Power factor >0.90
- Compact package: SO8
