High Performance Quad Output www.DataSheet4U.com Switching Regulator POWER MANAGEMENT Description The SC2463 is a high performance controller for multioutput converters that can be configured for a wide variety of applications. The SC2463 utilizes PWM synchronous buck topologies where efficiency is most important. It also provides two dedicated programmable positive linear regulators using external transistors. Each of the four outputs is adjustable down to 0.5V. The two PWM switchers are synchronized 180° out of phase reducing input ripple, allowing for fewer input capacitors. Power up sequencing prevents converter latch-up. The SC2463 can be synchronized to other converters to prevent beat frequencies.
