requiring a wide input voltage range. The high-side current sensing and an integrated current-setting circuitry minimize.
The HV9918 is a PWM controller IC designed to drive high brightness LEDs using a buck topology. It operates from an input voltage of 4.5 to 40VDC and employs hysteretic control with a high-side current sense resistor to set the constant output curren.
