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.
Features
◆ Two synchronized converters for low noise
◆ Power up sequencing to prevent latch-ups
◆ 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
◆ –40 to 105 degree C operating temperature
◆ Output voltage as low as 0.5V
◆ Small package TSSOP-28
Applications
◆ DSL applications with multiple input voltage requirements
◆ Mixed-Signal applications requiring positive and negative voltages
◆ Cable modem power management
◆ Base station power management
