Product details

Boost regulator for camera flash — 1.2 A peak, 5.5 V rail

The TPS61050AYZGR is a Texas Instruments step-up (boost) DC-DC regulator designed specifically for camera flash applications. It integrates the switching FET and delivers a regulated 5.5 V output at up to 1.2 A peak flash current, with PWM dimming control.

2 MHz switching and PWM dimming

The PWM dimming input lets the host controller set flash intensity or torch mode directly.
