FEATURES  
DESCRIPTION  
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.

•
•
•
Storage Capacitor Friendly Solution  
Automatic VF and ESR Calibration  
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.  
Power-Save Mode for Improved Efficiency at  
Low Output Power, Up to 95% Efficiency  
•
Output Voltage Remains Regulated When  
Input Voltage Exceeds Nominal Output Voltage  
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.

•
•
I2C Compatible Interface up to 3.4Mbits/s  
Zero Latency Tx-Masking Input  
Hardware Voltage Mode Selection Input  
(TPS61300, TPS61301)  
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
