General Description
The HV9910B is an open loop, current mode, control LED
driver IC. The HV9910B can be programmed to operate in
either a constant frequency or constant off-time mode. It
includes an 8.0 - 450V linear regulator which allows it to work
from a wide range of input voltages without the need for an
external low voltage supply. The HV9910B includes a 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.
The HV9910B is ideally suited for buck LED drivers. Since
the HV9910B operates in open loop current mode control, the
controller achieves good output current regulation without the
need for any loop compensation. PWM dimming response is
limited only by the rate of rise and fall of the inductor current,
enabling very fast rise and fall times. The HV9910B requires
only three external components (apart from the power stage)
to produce a controlled LED current making it an ideal solution
for low cost LED drivers.
