TPS61311YFFR TI LED Driver | 20-DSBGA | 40V, 1.5A Switch

Product Overview

The TPS61311YFFR from Texas Instruments is a high-voltage, high-frequency boost converter with an integrated 40V, 1.5A power switch. It is designed to drive up to 10 series white LEDs or provide a regulated output voltage up to 40V. The device operates with a switching frequency of 1.2 MHz, allowing the use of small external components. It features a programmable overvoltage protection (OVP) and supports both PWM and analog dimming for LED brightness control. The compact 20-DSBGA package (0.4mm pitch) makes it ideal for space-constrained applications.
