LED2000PUR ST LED Driver | 8-VFQFPN (4x4) | 3A, 850kHz

Product Overview

The LED2000PUR from STMicroelectronics is a high-efficiency, monolithic step-down DC-DC converter designed for driving high-brightness LEDs. It operates from an input voltage range of 4.5V to 38V and delivers up to 3A of output current. The device integrates a low RDS(on) N-channel power MOSFET and uses a current-mode control architecture for fast transient response and excellent loop stability. The switching frequency is internally set at 850kHz, allowing for small external components. The LED2000PUR is available in a compact 8-VFQFPN (4x4) package, making it suitable for space-constrained applications.
