HV9112

HV9110/HV9112/HV9113 High-Voltage Current-Mode PWM Controller Features Input Voltage Range of VDD Regulator - HV9110: 10V to 120V - HV9112: 9V to 80V - HV9113: 10V to 120V Maximum Duty, Feedback Accuracy - HV9110: 49%, 1% - HV9112: 49%, 2% - HV9113: 99%, 1% Current Mode Control <1 mA Supply Current >1 MHz clock Applications DC/DC Power Converters General Description HV9110/HV9112/HV9113 are Switch-Mode Power Supply (SMPS) controllers suitable for the control of a variety of converter topologies, including the flyback converter and the forward converter. The VDD regulator supports an input voltage as high as 80V or 120V. HV9110/HV9112/HV9113 controllers include all essentials for a power converter design, such as a bandgap reference, an error amplifier, a ramp generator, a highspeed PWM comparator, and a gate driver. A shutdown latch provides on/off control. The HV9110 and HV9113 feature an input voltage range of 10V to 120V, and the HV9112 has an input voltage...
