The LED5000PHR from STMicroelectronics is a high-efficiency, step-up LED driver specifically designed to meet the demands of high-brightness LED applications. This advanced power solution is ideal for driving a long string of LEDs with a constant current, ensuring uniform brightness and maximizing LED life.
With an input voltage range of 2.5V to 18V, the LED5000PHR is versatile and can accommodate various power sources, making it suitable for a broad range of products from portable devices to industrial lighting systems. The device is capable of providing an output voltage up to 35V, which allows it to drive multiple LEDs in series, ensuring consistent lighting across the string.
The LED5000PHR features an internal 60V N-channel MOSFET switch, which contributes to its high efficiency and helps to minimize external component count. It also supports a high switching frequency up to 1 MHz, enabling the use of small and low-cost inductors and capacitors, thus reducing the overall solution size and bill of materials.
Safety is a key consideration in any power management solution, and the LED5000PHR incorporates several protective features. These include overvoltage protection, which guards the device against surges that could potentially damage the LED string, and thermal shutdown to prevent overheating. Additionally, the device offers an open LED protection feature that prevents the output voltage from exceeding its maximum rated value in the event of an open LED condition.
The LED5000PHR is available in a compact VFQFPN 16L 3x3 mm package, which is ideal for space-constrained applications. Its excellent thermal performance and small form factor make it a go-to choice for designers looking to create sleek, efficient, and reliable LED lighting solutions.
Whether you are developing cutting-edge consumer electronics, automotive lighting, or professional-grade illumination systems, the LED5000PHR from STMicroelectronics offers the performance, efficiency, and reliability required to power your next-generation LED applications.
