WD3100
200mA Flash/Torch LED Driver
Descriptions
WD3100 is a low cost Flash/Torch LED driver
designed for front camera flash and small current
rear camera flash application.
WD3100 integrates a current sink to ensure constant
LED current when conditions such as VBAT voltage,
LED VF voltage, ambient temperature change.
The LED current can be adjusted by external resistor
connected between RSET pin and GND, and also
can be set to default 200mA by just simply connect
RSET pin to GND.
WD3100 has flash time-out protection function to
prevent LED lamp from overheating in abnormal
conditions.
