GP8510
Single Stage Buck PFC Controller for LED Lighting
Description
Features
The GP8510 is a single stage Buck PFC controller targeting at LED lighting applications. It drives the Buck converter in the quasiresonant mode to achieve higher efficiency. It keeps the Buck converter in constant on time operation to achieve high power factor. GP8510 is offered in SOT23-6 package.
• Valley turn-on of the MOSFET to achieve low switching losses.
• 0.3V current sense reference voltage leads to a lower sense resistance thus a lower conduction loss.
• Internal high current MOSFET driver: 0.25A sourcing and 0.5A sinking
• Low start up current: 12μA typical • Reliable short LED and Open LED protection • Power factor >0.9 with single-stage conversion.
