General Description
The HV9980 is a fully integrated 3-channel peak-current PWM controller for driving buck converters in constant output current mode. It is optimized for use with a large array of 20~80mA LED strings, where multiple HV9980 ICs are used sharing a common clock and a common reference voltage.

Features
► Integrated 200V, 25Ω (typ.) MOSFETs
► Programmable output current to 80mA per channel
► TTL compatible PWM dimming inputs
► 3-Phase synchronous operation
► Leading edge blanking
► Short circuit protection with skip mode
► Over-temperature protection

Applications
► LCD panel backlighting
► DLP RPTV or projector LED engine driver
► RGB decorative lighting
► General LED lighting
