FP7201
Constant Current Switching Regulator for White LED
General Description
The FP7201 is a Boost DC-DC converter specifically designed to drive white LEDs with constant
current. The device can support 2 to 7 white LEDs for backlighting and camera flashing. This high
efficient regulator and internal compensation network minimizes as 5 external component counts.
Optimized operation frequency can meet the requirement of small LC filters value and low operation
current with high efficiency. The non-inverting input of error amplifier connects to a 0.25V precision
reference voltage and internal soft-start function can reduce the inrush current.
The FP7201 is available in the TSOT23-6L package and provides space-saving PCB for diverse
application fields.
