Key Features
- Up to 1.2 A peak inductor current in a boost topology driving high-brightness white LEDs from a single-cell Li-ion input of 2.7 V to 5.5 V
- Serial I2C-compatible interface with 32-step current control for software-programmable LED brightness and flash/torch mode selection
- Compact 10-pin WSON package (3 x 3 mm) with integrated power switch enabling small camera flash and torch circuits with minimal external components
Applications
TPS61050DRCR is designed for camera flash and torch LED driver circuits in smartphones, tablets, and portable cameras requiring up to 1.2 A peak current from a 3.7 V lithium-ion cell. Its serial interface allows the host processor to select flash mode at full 1.2 A for short-duration exposures or torch mode at reduced current for continuous illumination. The boost architecture maintains regulated LED current even as the battery discharges below the LED forward voltage, extending usable camera flash runtime.

Frequently Asked Questions
What peak current and input voltage range does TPS61050DRCR support for camera flash applications?
TPS61050DRCR delivers up to 1.2 A peak switch current from an input voltage range of 2.7 V to 5.5 V, making it directly compatible with single-cell lithium-ion batteries at 3.7 V nominal. The boost converter topology maintains regulated LED current output as battery voltage drops, ensuring consistent flash brightness across the full discharge cycle of a 3.7 V cell.
How does the serial interface on TPS61050DRCR enable two-mode LED operation in a camera module?
TPS61050DRCR uses an I2C-compatible serial interface with a 7-bit address for host processor control. The interface provides 32 discrete current steps for brightness adjustment and separate flash versus torch mode register bits. Flash mode enables 1.2 A peak current for short 200 ms to 600 ms exposure bursts, while torch mode limits current to a lower continuous level of approximately 300 mA for video illumination without thermal runaway.
Can TPS61050DRCR drive LEDs in designs where the supply voltage is below the LED forward voltage?
Yes. TPS61050DRCR uses a boost switching topology operating at a fixed frequency, allowing it to step up a 2.7 V input to drive white LEDs with forward voltages of 3.2 V to 3.6 V. This is critical for camera flash circuits powered from a partially discharged lithium-ion cell near 3.0 V end-of-discharge voltage, where a linear driver would lose regulation.
What is the footprint of TPS61050DRCR and how does it fit into a smartphone camera module layout?
TPS61050DRCR is housed in a 10-pin WSON package measuring 3 x 3 mm with an exposed thermal pad on the bottom. This small footprint, combined with requiring only an external inductor of 2.2 µH to 4.7 µH and a few ceramic capacitors, enables a complete camera flash driver circuit in under 25 mm² of PCB area, suitable for the tight space constraints of smartphone camera module assembly.
