Product details

The TPS61054DRCR is a step-up (boost) DC-DC regulator from Texas Instruments, designed specifically for applications like camera flash and general lighting. It integrates the switching MOSFET internally, so the external BOM stays small: just the inductor, input/output caps, and a resistor for the PWM dimming control. The 2 MHz switching frequency supports a small inductor. The single output delivers up to 700 mA in flash mode.

New designs should not use this part; existing BOM lines need a replacement or a surplus-channel sourcing plan.

PWM dimming and supply voltage – design-in checklist

The PWM dimming input controls LED brightness directly from a microcontroller PWM pin. Supply voltage range is 2.5 V to 6 V, and the output is regulated to 5.5 V maximum. Surface-mount assembly: the 10-VSON package has a 3x3 mm footprint with an exposed thermal pad.
