The A718 is a monolithic switching regulator designed to
drive high power LEDs with constant current and is suitable for
automotive, industrial, and general lighting applications. The
step-down (Buck) regulator contains a high-side N-channel
MOSFET switch with a current limit of 1.5A. Hysteretic
controlled on-time and an external resistor allow the converter
output voltage to adjust as needed to deliver a constant current
to series and series-parallel connected LED arrays of varying
number and type.
