Краткое описание:
1.5-A and 4.1-A Multiple LED Camera Flash Driver With I2C Compatible Interface
Дополнительная информация
The TPS61300 is a high-frequency synchronous boost converter with constant current sinks designed to drive up to three white LEDs in parallel. It serves as a specialized power supply for high-peak current flash LEDs, utilizing a storage capacitor to minimize battery peak current demand. The device operates in four modes: DC light/flashlight, voltage regulated converter (3.8V to 5.7V), and standby. It features an I2C compatible interface, integrated LED safety timer, and zero-latency hardware trigger pins.
