The HV9911 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 or constant off-time mode. The HV9911 based LED driver is ideal for RGB backlight applications with DC inputs. The HV9911 based LED lamp drivers can achieve efficiency in excess of 90% for buck and boost applications.
