STMicroelectronics LED2001PUR
- Part Number:
- LED2001PUR
- Manufacturer:
- STMicroelectronics
- Ventron No:
- 3258113-LED2001PUR
- Description:
- IC LED DRVR RGLTR DIM 4A 8VFQFPN
- ECAD Model:
-
- Datasheet:
- LED2001PUR
Description
The LED2001 is a monolithic step-down DC-DC converter designed to operate as a precise constant current source with an adjustable current capability up to 4 A DC. It features a fixed switching frequency of 850 kHz, embedded PWM dimming circuitry for LED brightness control, and a regulated output current set by connecting a sensing resistor to the feedback pin. The embedded synchronous rectification and low RSENSE voltage drop enhance efficiency. The device is fully protected against thermal overheating, overcurrent, and output short-circuit. It is available in VFQFPN 4 mm x 4 mm 8-lead package and HSOP8.
Features
3.0 V to 18 V operating input voltage range
850 kHz fixed switching frequency
100 mV typ. current sense voltage drop
PWM dimming
± 7% output current accuracy
Synchronous rectification
95 mΩ HS / 69 mΩ LS typical Ros(on)
Peak current mode architecture
Embedded compensation network
Internal current limiting
Ceramic output capacitor compliant
Thermal shutdown
Applications
High brightness LED driving
Halogen bulb replacement
General lighting
