The SC2453 is a high performance controller for multi-output converters that can be configured for a wide variety of applications. The SC2453 utilizes PWM synchronous buck topologies where efficiency is most important. It also provides dedicated programmable positive and negative linear regulators using external transistors. Each of the three positive 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.
