Product details

Boost regulator sized for camera flash

The TPS61050DRCT is a step-up (boost) DC-DC regulator from Texas Instruments, purpose-built for driving a single white LED in camera flash applications. It delivers a regulated 5.5 V output at up to 1.2 A flash current, with PWM dimming control integrated on-chip.

Switching frequency and external component size

The 2 MHz switching frequency allows the use of small inductors and ceramic capacitors, shrinking the PCB footprint for compact camera modules or portable devices.

Operates from a 2.5 V to 6 V supply rail, covering single-cell Li-Ion and fixed 3.3 V or 5 V rails.

Housed in a 10-VSON (3x3 mm) with exposed pad for thermal dissipation.

Frequently asked questions

What is the closest functional second-source for TPS61050DRCT?

The LM2703MF-ADJ/NOPB is a step-up regulator from TI, but it is rated for backlight applications at 0.35 A output — significantly lower than the 1.2 A flash current of the TPS61050DRCT. For camera flash duty, the TPS61050DRCT is the correct choice.

What is the TPS61050DRCT's listed dimming method?

The TPS61050DRCT uses PWM dimming, allowing the LED brightness to be controlled by varying the duty cycle of the enable signal.
