Analog Simulation - HV9912
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 IC also includes a 0.2A source and 0.4A sink gate driver that makes the HV9912 suitable for high power applications. An internal 90V linear regulator powers the IC eliminating the need for a separate power supply for the IC. The HV9912 is a pin compatible replacement to HV9911. It is compatible with existing HV9911 designs which have an input voltage of less than 90V by changing ROVP1, ROVP, and RT.
