TPS61305A Overview
The TPS6130xx device is based on a high-frequency synchronous boost topology with constant current sinks to drive up to three white LEDs in parallel (400‑mA, 800-mA, and 400-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. The high-capacity storage capacitor on the output of the boost regulator provides the...
