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 PT5400 modules are packaged in a 5-pin thermally efficient copper case, which offers the advantage of solderability along with a small foot- print (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 cir- cuit protection, and thermal shutdown. A 100-µF input capacitor is required for proper operation. PT Series Suffix (PT1234x ) Case/Pin Order Package Configuration Suffix Code Vertical N (EFK) Horizontal A (EFL) SMD C (EFM) (Reference the applicable package code draw- ing for the dimensions and PC board layout) • On/Off Inhibit Function • Short Circuit Protection • Thermal Shutdown • Space-Saving package • Solderable Copper Case |
