Краткое описание:
1.5-A and 4.1-A Multiple LED Camera Flash Driver With I2C Compatible Interface
Дополнительная информация
The TPS61305 is a high-frequency synchronous boost topology device with constant current sinks designed to drive up to three white LEDs in parallel. It features an extended high-current mode (HC_SEL) allowing up to 1025-mA, 2050-mA, and 1025-mA flash current out of a storage capacitor. The device includes a 2-MHz switching frequency, I2C compatible interface up to 3.4 Mbits/s, and zero latency Tx-masking. It supports four operational modes: DC light/flashlight, voltage regulated converter (3.8 V to 5.7 V), and standby.
