Product details

Description

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.

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 signal for PWM dimming Over-temperature protection -40ºC to +125ºC operating temperature range General.
