HV9120 Datasheet (Microchip) - High-Voltage Current-Mode PWM Controller

HV9120, High-Voltage Current-Mode PWM Controller

HV9120 and HV9123 are Switch-Mode Power Supply (SMPS) controllers suitable for the control of a variety of converter topologies, including flyback and forward converter.

Using an internal, high-voltage regulator, HV9120 and HV9123 can derive a bias supply for starting-up and powering a converter fro
