General Description
The HV9930 is a variable frequency PWM controller IC
designed to control an LED lamp driver using a
low-noise boost-buck (Ćuk) topology. The HV9930
uses a patented Hysteretic Current-mode control to
regulate both the input and output currents. This
enables superior input surge immunity without the
necessity for complex loop compensation. Input
current control enables current limiting during Startup,
Input Undervoltage, and Output Overload conditions.
The HV9930 provides a low-frequency PWM dimming
input that can accept an external control signal with a
duty cycle of 0% to 100% and a high dimming ratio.
The HV9930-based LED driver is ideal for LED lamps
and RGB backlight applications with low-voltage DC
inputs. The HV9930-based LED Lamp drivers can
achieve efficiency in excess of 80%.
