TPS922055MDMTR TI LED Driver | 14-VSON(4.5X3) | 40V, 1.5A, PWM Dimming

Product Overview

The TPS922055MDMTR from Texas Instruments is a high-efficiency, synchronous boost LED driver designed for driving up to 10 series LEDs from a single-cell Li-ion battery. With an input voltage range of 2.5V to 40V and output current up to 1.5A, it integrates a 40V, 0.2Ω power MOSFET and supports PWM dimming for precise brightness control. The device operates at a fixed 2.2MHz switching frequency, enabling small external components. Protection features include overvoltage, overcurrent, and thermal shutdown.
