TPS92640PWPR/NOPB TI LED Driver | 14-HTSSOP | 4.5V-65V, 1.5A

Product Overview

The TPS92640PWPR/NOPB is a high-voltage, synchronous buck LED driver from Texas Instruments, designed for constant current regulation in automotive and industrial lighting applications. It operates over a wide input voltage range of 4.5V to 65V, delivering up to 1.5A of output current. The device integrates a low-side N-channel MOSFET and requires an external high-side MOSFET, enabling high efficiency and compact design. With a switching frequency adjustable from 100kHz to 2.2MHz, it offers flexibility in optimizing efficiency and solution size. The TPS92640PWPR/NOPB is housed in a 14-pin HTSSOP package with PowerPAD for enhanced thermal performance.
