Description

The SC2463 is a high performance controller for multi output 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. The wide range programmable operating frequency allows users to optimize a converter design. The PWM switchers sense the voltage across the low-side MOSFETs on-resistance to efficiently provide adjustable current-limit, eliminating costly current-sense resistors. A POK signal is issued when soft-start is complete on both PWM switchers and their outputs are within 10 of the set point.

Features

♦ Two synchronized converters for low noise
