Overview

FP7103 28V, 3A Buck Constant Current Switching Regulator for White LED General Description The FP7103 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 FP7103 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.
Features  Wide Supply Voltage Operating Range: 3.
6 to 28V  Built-in P-MOSFET for 3A Loading Capability  Precision Feedback Reference Voltage: 0.
25V (2%)  Low Current Consumption: 4mA  Internal Fixed Oscillator Frequency: 320KHz (Typ.
)  Internal Soft-Start Function (SS)...
