DESCRIPTION (CONTINUED)
Si9124 has advanced current monitoring circuitry to permit the
user to set the maximum current in the primary circuit. Such a
feature acts as protection against output shorts. Upon sensing
an overload condition, the converter is shut off for a period of
time and then soft-start cycle is re-initiated, achieving hiccup
mode operation. Current sensing is by means of a sense
resistor on the primary device. An integrated over-temperature
shutdown circuit also protects the system.
The 100-V depletion mode MOSFET integrated pre-regulator
circuit permits direct operation from input voltage with only one
series resistor during startup. The pre-regulator automatically
disconnects from the input supply when the output voltage is
established by means of a feedback winding from the filter
inductor.
Si9124 is available in TSSOP-16 pin package. In order to
satisfy the stringent ambient temperature requirements,
Si9124 is rated to handle the industrial temperature range of
–40 to 85
_C.
