General Description
The Supertex HV9904 is a second order PWM controller designed
to provide a constant average current output or a constant average
voltage output from an input of 10V to 400V DC or directly from
rectified AC mains up to 280V. The second order topology is
capable of extremely high dynamic control range, allowing
operation directly from rectified AC mains without the need for
bulky and expensive high voltage input electrolytic capacitor.
The PWM control utilizes feed forward circuitry to compensate for
large variations in input voltage (i.e. rectified AC) and a novel
integrator lock loop PLL scheme to regulate a differentially sensed
feedback node where the signal may be discontinuous. This
feedback node could be a current sense resistor or divider from
regulated output voltage. For a constant load the switching
frequency will be nearly constant with a dither of a few kHz helping
to meet FCC conducted emissions requirements.
A high input voltage linear regulator provides a stable Vdd supply
for the internal circuitry and gate drive to the external MOSFET.
Under voltage lockout provides a power on reset and protection for
the MOSFET
