HV9964
Overview
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.
