    Products Detail

    The PT5540 series are 12W integrated switching regulators (ISRs) that provide a fixed output voltage over the full industrial temperature range of -40°C to +85°C. They are designed for use with +5V bus systems that require an additional higher voltage rail. The series includes output voltages of +8V, +9V, +10V, +12V, +12.6V, and +15V. The modules are packaged in a 3-pin SMD thermally efficient copper case, which is solderable, has a small footprint, and can accommodate both through-hole and surface mount pin configurations. Applications include PCI cards, audio circuits, and battery operated instruments. The PT5540 series is a next generation replacement to the popular PT5040 series, with a lower operating temperature range and improved start-up characteristics.
