General Description
The FP7102 is a PWM control buck converter designed to provide a simple, high efficiency
solution for driving high power LEDs. With a 0.25V reference voltage feedback control to minimize
power dissipation, an external resistor sets the current as needed for driving various types of LEDs.
The FP7102 includes a high current P-MOSFET to realize high efficiency and excellent transient
characteristics. The PWM control circuit is able to change the duty ratio linearly from 0 up to 100%.
Other features include user accessible EN pin for enabling, thermal shutdown, cycle-by-cycle current
limit and over current protection.
