Download the LC5560LD datasheet PDF.
This datasheet also covers the LC5565LD variant, as both devices belong to the same off-line switching regulator ic family and are provided as variant models within a single manufacturer datasheet.
General Description
The LC5560LD series is the power IC for the non-isolated type LED
Key Features
Integrated on-time control circuit (it realizes high power factor by average current control).
Integrated startup circuit (no external startup circuit necessary).
Integrated soft-start circuit (reduces power stress during start-up on the incorporated power MOSFET and output rectifier).
Integrated bias assist circuit (improves startup performance, suppresses VCC voltage droop during operation, and allows use of low-rated ceramic capacitor on VCC pin).
