Product details

Boost regulator with I²C dimming for camera flash

The Texas Instruments TPS61300YFFT is a step-up (boost) DC DC regulator designed specifically for camera flash applications. It integrates three current-sink outputs, each capable of 400 mA continuous or 800 mA during the flash pulse, and uses an I²C interface for precise dimming control. The 1.92 MHz switching frequency allows the use of small external inductors and capacitors, which is essential for the tight PCB real estate inside a camera module or handheld device. The output is regulated to 5.7 V, matching the forward-voltage requirement of a typical series LED string.

Three-channel current sink and I²C bus

With three independent outputs, the TPS61300YFFT can drive a multi-LED flash array or separate flash and torch LEDs. The I²C dimming interface gives the host processor fine-grained control over each channel's current level, enabling pre-flash metering, exposure sequencing, and video light brightness adjustment without additional PWM pins. The device includes internal switches, so no external MOSFET is needed for the boost stage.

Housed in a 20-bump DSBGA (20-UFBGA) package, the TPS61300YFFT is a surface-mount device with a 0.50 mm ball pitch.

The base product number is TPS61300; the YFFT suffix denotes the 20-DSBGA package and tape-and-reel / cut-tape shipping options.

Frequently asked questions

Is TPS61300YFFT equivalent to TPS61300?

TPS61300 is the base product number; the YFFT suffix specifies the 20-DSBGA package and the tape-and-reel / cut-tape shipping format. The silicon is the same — the ordering code difference is purely packaging and handling.

How do I program the I²C dimming for TPS61300YFFT?

The I²C interface controls each of the three output channels independently. The host writes to the device's register map to set the current level for flash, torch, and indicator modes. The datasheet provides the register addresses and programming sequence.
