General Description

The HV9964 is a current mode control LED driver IC designed to control single switch PWM converters (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.

The IC also provides a load switch gate drive output, which can be used to disconnect the LEDs in case of a fault condition using an external load switch.

Key Features
