Description
The HV9980 is a fully integrated 3-channel peak-current PWM controller for driving buck converters in constant output current mode.
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.
