TECHNICAL DESCRIPTION
SiP11206 is a switching controller on the primary side of a
half-bridge intermediate bus converter. With 100 V depletion
mode MOSFET in the chip, the SiP11206 is capable of being
powered directly from the high voltage bus to V CC through an
external PNP pass transistor, or may be powered by an
external supply directly to the V CC pin.
Without the use of an external pass transistor, failure of the
converter output to power V CC above the V REG level will

result in over temperature protection activating hiccup
operation whenever the pre-regulator power dissipation
becomes excessive. The external high- and low-side
N-Channel power MOSFETs are driven by a built in driver
with ± 1.6 A peak current capability.
SiP11206 is available in the MLP44-16 PowerPAK ? package
and TSSOP-16 PowerPAK ? package and is specified over
the ambient temperature range of - 40 °C to + 85 °C
