Product details

Charge-pump LED driver for camera flash — 400 mA peak in a 3×3 mm WSON

The Texas Instruments LM2753SD is a switched-capacitor (charge pump) DC-DC regulator designed specifically for camera flash LED applications. PWM dimming input on the control pin lets the host processor set the flash intensity or run a movie-mode light without an external series resistor — the internal switch handles the current regulation.

Active production — single-source part, no direct second-source drop-in

RoHS compliance is not listed on this variant — the part is marked as RoHS non-compliant. Verify the latest TI environmental data sheet for your destination market before committing the BOM.

Frequently asked questions

What is the LM2753SD output current rating?

The LM2753SD delivers 400 mA per channel in flash mode.

Can the TLC5940RHBR replace the LM2753SD?

No. The TLC5940RHBR is a linear shift-register LED driver for backlighting with 120 mA per channel — it lacks the charge-pump topology and the 400 mA flash rating needed for camera flash. The LM2753SD is a switched-capacitor regulator; the two parts are not pin-compatible or functionally interchangeable.

What package does the LM2753SD use?

The LM2753SD comes in a 10-WFDFN exposed pad package (10-WSON, 3×3 mm). It is surface-mount and requires the exposed pad to be soldered to a PCB thermal plane.
