The PT5500 ExcaliburTM power modules are a series of high-performance Integrated Switching Regulators (ISRs). Rated 3A, these modules operate from input voltages as low as 3.1V to provide a local step-down power source. They are an ideal compliment to the industry's latest high-performance DSPs and microprocessors. The series includes output voltage options as low as 1.0VDC. The PT5500 series is packaged in a 5-pin thermally efficient copper case. The case is solderable, has a small footprint, and can accommodate both through-hole and surface mount pin configurations.
