PT5402C [Texas Instruments]

The PT5400 Excalibur™ power modules are a series of high-performance integrated switching regulators (ISRs) based on TI’s SWIFT (Switcher With Integrated FET Technology) regulator ICs. These ready-to-use modules are rated for up to 6 A of output current from input voltages as low as 3.1 V, providing a convenient step-down power source for the industry’s latest high-performance DSPs and microprocessors. The series includes output voltage options as low as 1.0 VDC. The modules are packaged in a 5-pin thermally efficient copper case, which offers the advantage of solderability along with a small footprint (0.355 in², suffix ‘N’). Both through-hole and surface mount pin configurations are available. The product features external output voltage adjustment, an on/off inhibit function, short circuit protection, and thermal shutdown. A 100-µF input capacitor is required for proper operation.
