The A718 is a Buck-type switching regulator designed to drive high power LEDs with constant current and is suitable for automotive, industrial, and general lighting applications. This Buck (step-down) regulator contains a high-side N-channel power MOS switch with a current limit of 1.5A. An external resistor allows the converter output voltage to adjust as needed to deliver a constant current to series and series-parallel connected LED strings of varying number and type.
The A718 provides open/short circuit protection and thermal shutdown protection. LED dimming control can be accomplished by pulse width modulation (PWM) via PWM pin.
