Feed-Forward Controller with Primary MOSFET  
Drivers for Intermediate Bus Converters  
DESCRIPTION  
FEATURES  
36 V to 75 V input voltage range  
SiP11205 is a feed-forward controller for the primary side of  
a half-bridge intermediate bus converter (IBC). It is ideally  
suited for isolated applications such as telecom, data  
communications and other products requiring an IBC  
architecture and conversion of standard bus voltages such  
as 48 V to a lower intermediate voltage, where high  
efficiency is required at low output voltages (24 V, 12 V, 9 V  
or 5 V).  
Withstand 100 V, 100 ms transient capability  
Integrated 1.6 A typical high- and low-side MOSFET  
drivers  
Oscillator frequency is programmable from 200 kHz to  
1 MHz (100 kHz to 500 kHz switching frequency) and can  
be externally synchronized  
Voltage feed-forward compensation  
High voltage pre-regulator operates during start-up  
Current sensing on primary low-side switch  
Hiccup mode  
System low input voltage detection  
Chip UVLO function  
Designed to operate within the telecom voltage range of  
36 V to 75 V and withstand 100 V transients for a period of  
100 ms, the IC is designed for controlling and driving both  
the low- and high-side switching devices of a half-bridge  
converter.  
Programmable soft-start function  
Over temperature protection (160 °C)  
Greater than 95.5 % efficiency for 42 V to 55 V input range  
The feed-forward feature is designed to make the converter  
output semi-regulated and is beneficial for point-of-load  
applications that require narrow input range. SiP11205 has  
advanced current monitoring and control circuitry, which  
allows the user to set the maximum current in the primary  
circuit. This feature acts as protection against overcurrent  
and output short circuit. Current sensing is by means of a  
sense resistor connected in series with the primary low-side  
MOSFET.  
Better than 2 % line regulation at 9 A
