Overview

The HV9980B1 demoboard is an RGB or multi-channel white LED backlight driver designed to drive LEDs for a large-screen TV. The HV9980DB1 can drive three common-anode LED strings from a 100 - 140V input at currents up to 70mA in steady state. It can also drive the LEDs at currents as large as 160mA for short durations to facilitate backlight scanning mode.  Each of the three channels can be individually controlled by PWM dimming. The demoboard is also protected from short circuit conditions across any string and recovers automatically once the condition disappears.
