Half-Bridge Controller with Primary MOSFET Drivers for

Intermediate Bus Converters

DESCRIPTION

FEATURES

•

36 V to 75 V input voltage range

SiP11206 is a 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 and can be externally synchronized

High voltage pre-regulator operates during start-up

Current sensing on primary low-side switch

Hiccup mode

•

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.

System low input voltage detection

Chip UVLO function

Programmable soft-start function

Over temperature protection (160 °C)

• Greater than 95 % efficiency

The SiP11206 operates with a fixed duty cycle to provide the

highest efficiency over a wide input voltage range. SiP11206

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,

output short circuit. Current sensing is by means of a sense

resistor connected in series with the primary low-side

MOSFET.
