LP5899DYYR TI LED Driver | 14-SOT-23-THIN | 40V, 150mA, 1MHz

Product Overview

The LP5899DYYR from Texas Instruments is a high-efficiency, constant-current LED driver designed for a wide range of lighting applications. Housed in a compact 14-SOT-23-THIN package, this device integrates a boost converter with an internal 40V, 150mA switch, enabling it to drive up to 10 series LEDs from a single Li-Ion cell. With a switching frequency up to 1MHz, it allows for small external components, making it ideal for space-constrained designs.
