PT6440

PT6440 Series 6-A 5-V/3.3-V Input Adjustable Integrated Switching Regulator Features 6A Output Current Input Voltage Range: 3.1 V to 5.5 V 90% Efficiency Adjustable Output Voltage Standby Function Short Circuit Protection Small Footprint (0.61 in2) Solderable Copper Case 8.8 106 Hours MTBF SLTS133B Revised (1/30/2002) Description 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 100µF input, and 330µF output capacitor are required for proper operation.
