HV9918 High Brightness LED Driver

HV9918 Description

HV9918 Hysteretic, Buck, High Brightness LED Driver with High-Side Current Sensing .
The HV9918 is a PWM controller IC designed to drive high brightness LEDs using a buck topology.

HV9918 Features

* Hysteretic control with high-side current sensing Integrated 40V 1.0Ω MOSFET >90% Efficiency Wide input voltage range: 4.5 to 40V ±5% LED current accuracy Up to 2.0MHz switching frequency Adjustable constant LED current Analog or PWM control

HV9918 Applications

* requiring a wide input voltage range. The high-side current sensing and an integrated current-setting circuitry minimize the number of external components while delivering an accurate average output. Dedicated pulse-width modulation (PWM) input enables pulsed LED dimming over a wide range of brightn
