HV9912, Switch-mode LED Driver IC

The HV9912 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 a
