PT6440

The PT6440 Excalibur™ power modules are a series of high performance Integrated Switching Regulators (ISRs), housed in a thermally efficient solderable copper case. These modules operate from input voltages as low as 3.1V to produce a high-output lowvoltage power source; ideal for powering the industry's latest DSP and microprocessors. The series includes standard output bus voltages as low as 1.0VDC. The innovative copper case construction provides superior thermal performance in a small footprint. Both through-hole and surface mount pin configurations are available.

The PT6440 series operating features include external output voltage adjustment, an On/Off inhibit, and short-circuit protection. A 100F input, and 330F output capacitor are required for proper operation.
