| FP7101A 2A Constant Current Buck Converter for powering LEDs | |||||||
General Description | Download | ||||||
| The FP7101A is a current-mode buck regulator with a built in internal 2Apower MOSFET. It provides a simple, high efficiency solution for driving high power LEDs. With a 0.2V reference voltage feedback control to minimize power dissipation, an external resistor sets the current as needed for driving various types of LEDs. Current mode operation provides fast transient response and eases loop stabilization. The FP7101A requires a minimum number of readily available external components to complete a 2A buck regulator design. The device also includes cycle-by-cycle current limiting and thermal shutdown protection. Additional features include user accessible EN/DIM pin for enabling and PWM dimming of LEDs. |
