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.
Key Features
- 3-Channel LED Array Driver IC 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 illumination. The output currents are programmed by controlling peak source current in each of the three internal 200V, 25Ω switching MOSFETs. The peak current is detected by monitoring v.
