Description
The SC2453 is a high performance controller for multioutput 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 latchup.
Features
◆ Two synchronized converters for low noise
◆ Power up sequencing to prevent latch-up
◆ Out of phase operation for low input ripple
◆ Over current protection
◆ Wide input range, 4.5 to 30V
◆ Programmable frequency up to 700KHz
◆ Two synchronous bucks for high efficiency at high current
◆ One dedicated programmable positive linear regulator and one dedicated programmable negative linear regulator
◆ Output voltage as low as 0.5V
◆ Small package TSSOP-28. Also offered in lead free, WEEE and RoHS compliant package
Applications
◆ DSL applications with multiple input voltage requirements
◆ Mixed-Signal applications requiring positive and negative voltages
◆ Cable modem power management
◆ Base station power management
