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.
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.
