HV9985 - LED Driver

The HV9985 is a three-channel peak current mode PWM controller for driving single switch converters in a constant output current mode.

It can be used for driving either RGB LEDs or multiple channels of white LEDs.

• Switch mode controller for single-switch converters.
• Gate drivers optimized for driving Logic Level FETs.
• 0.25A sourcing.
• 0.5A sinking.
• Typical ±2% absolute and string-to-string current accuracy (with ±1% sense resistors).
• High PWM dimming ratio up to 5000:1.
• 10-40V input range.
• Constant frequency operation up to 1.0MHz.
• On-chip clock or external clock option.
• Programmable slope compensation.
• Linear and PWM dimming.
• Output shor.
