The TPS61151DRCR from Texas Instruments is a high-frequency boost converter featuring two regulated current outputs specifically for driving white LEDs (WLEDs). Each output can be individually programmed using external resistors, and dedicated selection pins allow for separate or simultaneous activation of the two outputs.
This device operates with an input voltage range of 2.5-V to 6-V, and each output can reach up to 27 V. It incorporates a 0.7-A integrated switch and runs at a fixed 1.2-MHz PWM frequency. The output current can be adjusted via a PWM signal on the SEL pins or an analog voltage on the ISET pins, enabling PWM dimming of the WLEDs. The converter achieves up to 83% efficiency and supports a PWM dimming frequency of up to 30 kHz.
The TPS61151DRCR is housed in a 10-VSON (3x3) package and is designed for surface mount applications. It operates within a temperature range of -40°C to 85°C.
