Description
General part information
TPS61325 Series
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 (445-mA, 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.
The 2-MHz switching frequency allows the use of small and low profile 2.2-μH inductors. To optimize overall efficiency, the device operates with a 400-mV LED feedback voltage.
