GENERAL DESCRIPTION
The HV9860 is a current mode control LED driver IC designed to control a boost or flyback LED driver in constant frequency mode. The controller uses a peak current-mode control scheme and includes an internal transconductance amplifier to accurately control the output current over all line and load conditions. The IC also provides a disconnect switch gate drive output, which can be used to achieve good PWM rise and fall times for the LED current using an external disconnect FET. The HV9860 also has a DUTY pin which can be used to set the maximum duty cycle to either 90%(typ) or 75%(typ). The 75% duty cycle limit can be used for flyback applications. The HV9860 also provides a TTL compatible, low-frequency PWM dimming input that can accept an external control signal with a duty ratio of 0-100% and a frequency of up to a few kilohertz. The HV9860 includes a wiring fault detection function that sends a flag to the boost input power supply in case of an LED to...
