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 V_DD regulator supports an input voltage as high as
80V or 120V.
HV9110/HV9112/HV9113 controllers include all essen-
tials for a power converter design, such as a bandgap
reference, an error amplifier, a ramp generator, a high-
speed 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 range of 9V to 80V. The HV9110 and HV9112
have a maximum duty of 49%, while the HV9113 has a
maximum duty of 99%.
