MR16專用驅(qū)動IC, 可替代PT4115 (帶紅外搖控調(diào)光)

LD1610

The LD1610 is a continuous mode inductive step-down converter, designed for driving single or multiple series connected High Power LEDs with a minimum number of external components. It operates from an input voltage range of 7V to 40V and provides an externally adjustable output current up to 1.0A depending upon input voltage and external components. The LD1610 has internal switching transistor, regulator and output current sensing circuit, which uses an external resistor to set the nominal average output current. The LED dimming can be controlled via pulse width modulation (PWM) through DIM pin. Additionally, to ensure the system reliability, the LD1610 has internal thermal shutdown circuit.
 
7V ~ 40V input range is generation maximum 1.0A output constant current.
Regulation voltage is 4.5V
Over temperature thermal protection
Over voltage circuit protection
External dimming control PIN
Package : 8-pin exposed SOP
APPLICATION
MR16 Lighting
DC/DC LED Driver
Automotive Lighting
Offline LED Lamps
