Дополнительная информация
The TPS61301 is a high-frequency synchronous boost topology device with constant current sinks designed to drive up to three white LEDs in parallel. It serves as a flash LED driver and a standard voltage boost regulator. The device features a storage capacitor friendly solution to reduce peak current demand from the battery, and includes an extended high-current mode (HC_SEL) allowing up to 1025-mA, 2050-mA, and 1025-mA flash current out of the storage capacitor.
