The PT6340 ExcaliburTM power modules are a series of high performance Integrated Switching Regulators (ISRs), housed in a thermally efficient solderable copper case. These modules operate from a 12V input voltage bus 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 ranging from 5VDC to 1.2VDC. The innovative copper case construction provides superior thermal performance in a small footprint. Both through-hole and surface mount pin configurations are available. The PT6340 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.
