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
