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 2A power 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.
Features
Wide 4.75 to 23V Operating Input Range
Output Adjustable From 0.2 to 16V
2A Output Current
0.22Ω Internal Power MOSFET Switch
Fixed 380KHz Frequency
Up to 90% Efficiency
25μA Shutdown Mode Current
Stable with Low ESR Output Ceramic Capacitors
Cycle-by-Cycle Over Current Protection
Under Voltage Lockout
Thermal Shutdown
Available SOP-8L & SOP-8L (EP) Package
