High Performance Quad Output Switching
Regulator
POWER MANAGEMENT Description
SC2453 is a high performance multi-output converter controller that can be configured for a variety of applications.
The SC2453 utilizes synchronous rectified buck topologies where efficiency is most important.
It also provides dedicated programmable positive and negative linear
regulators using external
transistors in conjunction with coupled windings to generate positive and negative voltages.
Power up sequencing prevents converter latchups.
The two buck converters are out of phase, reducing input ripple, allowing for fewer input capacitors.
All converters are synchronized to prevent beat fre...
