TPS61310 具有 12C 兼容接口的 1.5A 多个 LED 摄像机闪存驱动器

TPS61310 描述

The TPS6131x family is an integrated solution with a wide feature set for driving up to three LEDs for still-camera flash strobe and video-camera lighting applications. It is based on a high efficiency synchronous boost topology with combinable current sinks to drive up to three white LEDs in parallel. The 2MHz switching frequency allows the use of small and low-profile 2.2µH inductors. To optimize overall efficiency, the device operates with a low LED-feedback voltage and regulated output-voltage adaptation. The device integrates a control scheme that automatically optimizes the LED current flash budget as a function of the battery voltage condition. The TPS6131x not only operates as a regulated current source, but also as a standard voltage boost regulator
