DESCRIPTION  
The Si9108 high-voltage switchmode regulator is a monolithic  
BiC/DMOS integrated circuit which contains most of the  
components necessary to implement a high-efficiency dc/dc  
converter in ISDN terminals up to 3 watts. A 0.5-mA max  
supply current makes possible the design of a dc/dc converter  
with 60% efficiency at 25 mW, therefore meeting the  
recommended performance under the CCITT I.430  
specifications.  
This device may be used with an appropriate transformer to  
implement isolated flyback power converter topologies to  
provide single or multiple regulated dc outputs (i.e., "5 V).  
The Si9108 is available in both standard and lead (Pb)-free  
16-pin wide-body SOIC, 14-pin plastic DIP and 20-pin PLCC  
packages which are specified to operate over the industrial  
temperature range of −40_C to 85_C.

DETAILED DESCRIPTION  
Pre-Regulator/Start-UpSection  
Error Amplifier  
Closed-loop regulation is provided by the error amplifier,  
whose 1-kꢂ dynamic output impedance enables it to be used  
with feedback compensation (unlike transconductance  
amplifiers). A MOS differential input stage provides for low  
input current. The noninverting input to the error amplifier  
(VREF) is internally connected to the output of the reference  
supply and should be bypassed with a small capacitor to  
ground.  
Due to the low quiescent current requirement of the Si9108  
control circuitry, bias power can be supplied from the  
unregulated input power source, from an external regulated  
low-voltage supply, or from an auxiliary “bootstrap” winding on  
the output inductor or transformer.  
When power is first applied during start-up, +VIN will draw a  
constant current. The magnitude of this current is determined  
by a high-voltage depletion MOSFET device which is  
connected between +VIN and VCC. This start-up circuitry  
provides initial power to the IC by charging an external bypass  
capacitance connected to the VCC pin. The constant current is  
disabled when VCC exceeds 9.3 V. If VCC is not forced to  
exceed the 9.3-V threshold, then VCC will be regulated to a  
nominal value of 9.3 V by the pre-regulator circuit.  
Oscillator Section  
The oscillator consists of a ring of CMOS inverters, capacitors,  
and a capacitor discharge switch. Frequency is set by an  
external resistor between the OSC IN and OSC OUT pins.  
(See Typical Characteristics graph of resistor value vs.  
frequency.) The DISCHARGE pin should be tied to −VIN for  
normal internal oscillator operation. For 98% duty cycle, the  
discharge pin must be connected to −VIN or can be connected  
to −VIN through a resistor to set the dead time.  
As the supply voltage rises toward the normal operating  
conditions, an internal undervoltage (UV) lockout circuit keeps  
the output MOSFET disabled until VCC exceeds the  
undervoltage lockout threshold (typically 8.7 V). This  
guarantees that the control logic will be functioning properly  
and that sufficient gate drive voltage is available before the  
MOSFET turns on. The design of the IC is such that the  
undervoltage lockout threshold will not exceed the  
pre-regulator turn-off voltage. Power dissipation can be  
minimized by providing an external power source to VCC such  
that the constant current source is always disabled.  
Remote synchronization can be accomplished by capacitive  
coupling of a synchronization pulse into the OSC IN terminal.  
For a 5-V pulse amplitude and 0.5-ꢀs pulse width, typical  
values would be 100 pF in series with 3 kꢂ to OSC IN.  
SHUTDOWN and RESET  
SHUTDOWN and RESET are intended for overriding the  
output MOSFET switch via external control logic. The two  
inputs are fed through a latch preceding the output switch.  
Depending on the logic state of RESET, SHUTDOWN can be  
either a latched or unlatched input. The output is off whenever  
SHUTDOWN is low. By simultaneously having SHUTDOWN  
and RESET low, the latch is set and SHUTDOWN has no effect  
until RESET goes high. (See the table below.)  
BIAS  
To properly set the bias for the Si9108, a 820-kꢂ resistor  
should be tied from BIAS to −VIN. This determines the  
magnitude of bias current in all of the analog sections and the  
pull-up current for the SHUTDOWN and RESET pins. The  
current flowing in the bias resistor is nominally 7.5 ꢀA.

Normal Operation  
Normal Operation (No Change)

The reference section of the Si9108 consists of a temperature  
compensated buried zener and trimmable divider network.  
The output of the reference section is connected internally to  
the non-inverting input of the error amplifier. Nominal reference  
output voltage is 4 V. The trimming procedure that is used on  
the Si9108 brings the output of the error amplifier (which is  
configured for unity gain during trimming) to within "1% of 4 V.  
This automatically compensates for the input offset voltage in  
the error amplifier.

When power is first applied during start-up, +VIN will draw a

by a high-voltage depletion MOSFET device which is  
connected between +VIN and VCC. This start-up circuitry  
provides initial power to the IC by charging an external bypass  
capacitance connected to the VCC pin. The constant current is  
disabled when VCC exceeds 9.3 V. If VCC is not forced to  
exceed the 9.3-V threshold, then VCC will be regulated to a  
nominal value of 9.3 V by the pre-regulator circuit.  
The output impedance of the reference section has been  
purposely made high so that a low impedance external voltage  
source can be used to override the internal voltage source, if  
desired, without otherwise altering the performance of the  
device.

DETAILED DESCRIPTION (CONT’D)  
Both pins have internal current source pull-ups and can be left  
disconnected when not in use. An added feature of the current  
sources is the ability to connect a capacitor and an  
open-collector driver to the SHUTDOWN pin to provide  
variable shutdown time.  
Output Switch  
The output switch is a 7-ꢂ , 200-V lateral DMOS transistor. Like  
discrete MOSFETs, the switch contains an intrinsic body-drain  
diode. However, the body contact in the Si9108 is connected  
internally to −VIN and is independent of the SOURCE.
