IPC Lead Free 2
Description
The PT5540 Excalibur鈩?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擄C to +85擄C. 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.
