TS19370 - Boost (Step-up) WLED Driver

Taiwan Semiconductor

Datasheet Details

The TS19370 is a step-up DC/DC converter specifically designed to drive white LEDs with a constant current.

The device can drive 2 ~ 9 LEDs in series from a Li-Ion cell.

Series connection of the LEDs provides identical LED currents resulting in uniform brightness and eliminating the need for ballast resistors.
