Hysteretic, Buck, High Brightness LED Driver w/ High-Side Current Sensing

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 current up to 700mA. The device is well suited for appli Hysteretic control with high-side current sensing\nIntegrated 40V 1.0O MOSFET\n>90% Efficiency\nWide input voltage range: 4.5 to 40V\n±5% LED current accuracy\nUp to 2.0MHz switching frequency\nAdjustable constant LED current\nAnalog or PWM control signal for PWM dimming\nOver-temperature pr;
