Description
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 from a variety of power sources,
such as a 12V battery or the rectified AC (230 VAC)
line.
HV9120/HV9123 controllers include all essentials 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. Device power consumption is
less than 6 mW when shutdown.
HV9120 offers 50% maximum duty and HV9123 offers
nearly 100% duty.
