Vishay Siliconix
Low Power Consumption Current Mode Controller
DESCRIPTION
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
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.
FEATURES
• Pin-for-pin compatible with UCC280X
controllers
• Enhanced performance UC284X
for new designs
• 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
• Compliant to RoHS Directive 2002/95/EC
APPLICATIONS
• Efficiency-enhanced DC/DC converter modules
• Low quiescent current standby power supplies
• Offline (AC/DC) power supplies
• Universal input power supplies
• Buck, boost, and buck-boost converters
