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
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.

Notes:
a. Currents are positive into, negative out of the specificed terminal.
b. In normal operation V
CC
is powered through a current limiting resistor. An absolute maximum of 12 V applies when V
CC
is driven from a low
impedance source such that I
CC
does not exceed 30 mA.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation
of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect device reliability.
