The TPS61500PWPR from Texas Instruments is a monolithic switching regulator designed as a high-brightness LED driver. It features an integrated 3-A, 40-V power switch, making it suitable for driving 1-W or 3-W LEDs. The device accepts an input voltage ranging from 2.9 V to 18 V and can provide an output voltage up to 38 V. Its switching frequency can be set externally from 200 kHz to 2.2 MHz, with a maximum duty cycle of 93%.
This LED driver offers high-efficiency power conversion, reaching up to 93%. It supports both analog and PWM dimming for brightness control and includes user-defined soft-start functionality and programmable overvoltage protection. The TPS61500PWPR is housed in a 14-pin HTSSOP package with PowerPAD technology, designed for surface mounting. Its operating temperature range is -40°C to 85°C.
Key electrical characteristics include a typical LED current of 400 mA per channel and a boost topology. The device is suitable for backlight applications and offers flexibility in design due to its adjustable switching frequency and dimming capabilities.
