PT5540

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 -40 to +85. 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.
