TPS61325 Datasheet 1.5-a To 4.1-a Multiple Led Camera Flash Driver

Manufacturer: Texas Instruments

Overview: Product Folder Sample & Buy Technical Documents Tools & Software Support & munity TPS61325, TPS61326 SLVS977B – FEBRUARY 2010 – REVISED JULY 2016 TPS6132x 1.5-A to 4.

General Description

The TPS6132x device is based on a high-frequency synchronous boost topology with constant current sinks to drive up to three white LEDs in parallel (445mA, 890-mA, 445-mA maximum flash current).

The extended high-current mode (HC_SEL) allows up to 1025-mA, 2050-mA, and 1025-mA 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.

Key Features
