12-W 5-V Input Step-Up (Boost) Integrated Switching Regulator

The PT5540 Excalibur Power Modules are a series of integrated Switching Regulators (ISRs) that provide a boost-voltage function. They are designed for use with +5V bus systems that require an additional higher voltage rail. The modules are rated 12W and produce a fixed output voltage over the full industrial temperature range of -40C to +85C. The series includes the common output voltages, +12V and +15V. Applications include PCI cards, Audio circuits, and battery operated instruments. The PT5540 series is packaged in a 3-pin thermally efficient copper case. The case is solderable, has a small footprint, and CAN accommodate both through-hole and surface mount pin configurations. The PT5540 series is offered as a next generation replacement to the popular PT5040 series. The PT5540 has a lower operating temperature range and improved start-up characteristics.
