SLVS978D – MARCH 2010 – REVISED SEPTEMBER 2016 TPS6131x 1.5-A Multiple LED Camera Flash and Video Light Driver
With I2C Compatible Interface
1 Features 3 Description The TPS6131x family is an integrated solution with a
wide feature set for driving up to three LEDs for stillcamera 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
2-MHz switching frequency allows the use of small
and low-profile 2.2-ВµH inductors. To optimize overall
efficiency, the device operates with a low LEDfeedback voltage and regulated output-voltage
adaptation. 1 Operational Modes:
– Video Light and Flash Strobe
– Voltage Regulated Converter: 3.8 V to 5.7 V
With Down Mode
– Standby: 2 µA (Typical)
