| Part Number | LC5550LD |
| Manufacturer | Sanken (https://www.sanken-ele.co.jp/) |
| Description | LC5550LD series are PWM and quasi-resonant topology non-isolated buck LED driver ICs. They incorporate separate controller and power MOSFET chips, and are designed for input capacitorless applications... |
| Features |
• PWM and quasi-resonant topology • Integrated on-time control circuit (it realizes high power factor by average current control) • 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) • Integrated Leading Edge Blanking (LEB) circuit • Integrated maximum on-time limit circuit • Protection features: ▫ Overcurrent protection (OCP): pulse-by-pulse ▫ Overvoltage ... |
