TPS61325 Overview
Description
The TPS6132x device is based on a high-frequency synchronous boost topology with constant current sinks to drive up to three white LEDs in parallel (445mA, 890-mA, 445-mA maximum flash current). The extended high-current mode (HC_SEL) allows up to 1025-mA, 2050-mA, and 1025-mA flash current out of the storage capacitor.
