产品描述

The TPS6130x device is based on a high-frequency synchronous boost topology with constant current sinks to drive up to three white LEDs in parallel (400mA/800mA/400mA maximum flash current). The extended high-current mode (HC_SEL) allows up to 1025mA/2050mA/1025mA flash current out of the storage capacitor.

The high-capacity storage capacitor on the output of the boost regulator provides the high-peak flash LED current, thereby reducing the peak current demand from the battery to a minimum.

The 2-MHz switching frequency allows the use of small and low profile 2.2µH inductors. To optimize overall efficiency, the device operates with a 400mV LED feedback voltage.

The TPS6130x device not only operates as a regulated current source, but also as a standard voltage boost regulator. The device keeps the output voltage regulated even when the input voltage exceeds the nominal output voltage. The device enters power-save mode operation at light load currents to maintain high efficiency over the entire load current range.

To simplify flashlight synchronization with the camera module, the device offers a trigger pin (FLASH_SYNC) for zero latency LED turn-on time.
