Function and description
This is the power MOSFET drain for the Catch device. It connects to the output inductor and the
positive of the forward converter transformer secondary.
This is the power MOSFET Drain for the forward device. This pin connects to the negative of
the forward converter transformer secondary.
The signal reference for external tailoring parts.
This is the input signal to the linear regulator. It can be used as an input in low output voltage
applications where the peak voltage on the MOSFETs is not high enough to operate the
regulator.
5V regulator output. It is also available for use with feedback circuitry that is on the secondary
side. This is useful in low voltage converters where the voltage is too low to operate optical
couplers directly from the output.
This is the common of the power MOSFET synchronous rectifiers
Pin 7 is used to ensure that the transformer can be reset during light load operation. To allow
reset, the forward drive is inhibited for a time before the turn on of the Catch MOSFET Gate.
Pin 8 is used for an external capacitor to tailor the prediction time for the Catch synchronous
rectifier.
Pin 9 is used to tailor the module’s ability to differentiate between valid turn off of the Catch
MOSFET and ringing that can occur at light load.
