Low Power Consumption Current Mode Controller
DESCRIPTION
FEATURES
The SiP280X family includes six high-speed, low power
consumption, BiCMOS Current Mode Controllers. These
integrated circuits contain all of the control and drive
functions required for off-line and DC/DC current-mode
? Pin-for-pin compatible with UCC280X
controllers
? Enhanced performance UC284X

switching power supplies. Their advanced architecture
enables the implementation of full-featured designs with
minimal external parts count.
The SiP280X family controllers is available in lead (Pb)-free,
SO-8 packages, and are rated for operation over the
industrial temperature range of -40 °C to 85 °C.
? 100 μA typical start-up current
? 500 μA typical operating current
? Internal soft start at power-on and after fault
? 100 ns internal leading edge blanking
