General Description
TheHV9910C is an open loop, current mode, control LED driver IC. The HV9910C
can be programmed to operate in either a constant frequency or constant off-
time mode. It includes a
15 – 450V linear regulator which allows it to work from a wide range of input
voltages without the need for an external low voltage supply. HV9910C includes
a TTL compatible 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. It
also includes a 0 – 250mV linear dimming input which can be used for linear
dimming of the LED current. As opposed to the HV9910B, the HV9910C is equipped
with built-in thermal shutdown protection.
