LED2001PHR ST LED Driver | 8-HSOP | 4A, 61V, 850kHz

Product Overview

The LED2001PHR from STMicroelectronics is a high-efficiency, monolithic step-down current source designed to drive high-brightness LEDs. It operates from an input voltage range of 4.5V to 61V and delivers a constant output current up to 4A. The device integrates a power MOSFET and a high-side current sensing circuit, enabling a compact solution with minimal external components. The switching frequency is adjustable up to 850kHz, allowing for optimized trade-offs between efficiency and component size. The LED2001PHR is housed in an 8-lead HSOP package with exposed pad for enhanced thermal performance.
