HV9963NG-G General Description

The HV9963 is a current mode control LED driver IC designed to control single switch PWM converters (buck, boost, buck-boost or SEPIC) in a constant frequency mode. The controller uses a peak current-mode control scheme (with programmable slope compensation) and includes an internal transconductance amplifier to accurately control the output current over all line and load conditions. Multiple HV9963s can be synchronized to each other or to an external clock using the SYNC pin. The IC also provides a disconnect switch gate drive output, which can be used to disconnect the LEDs in case of a fault condition using an external disconnect FET. The 10V external FET drivers allow the use of standard level FETs. The low voltage 5.0V AVDD is used to power the internal logic and also acts as a reference voltage to set the current level.The HV9963 includes an enhanced PWM dimming logic (patent pending) that enables very high PWM dimming ratios.The HV9963 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 tens of kilohertz.
