Si9113 is a current mode PWM controller for ISDN power
supplies. In a 14-pin SOIC package, it provides all necessary
functions to implement a single-switch PWM with a minimum
of external parts. To maximize the circuit integration, the
Si9113 is designed with a 200-V depletion mode MOSFET
capable of powering directly off the high input bus without an
external start-up circuit. The Start and Stop input voltage
thresholds can be programmed within the operating input
voltage range by means of a resistor divider, provided +V
IN
(Start) > +V
IN
(Stop). The internal clock frequency is set with
a single external resistor and is capable of capacitor-coupled
external synchronization. In order to satisfy the stringent
ambient temperature requirements, the Si9113 is rated to
handle the industrial range of –40 C to 85 C.
