Switching Regulator, Voltage-mode, 7.5A, 63kHz Switching Freq-Max, BIPolar, PSSO5, TO-263, 5 PIN Always verify details of parts you are evaluating, as these parts are offered as suggestions for what you are looking for and are not guaranteed.ħ.5A SWITCHING REGULATOR, 63kHz SWITCHING FREQ-MAX, PSSO5, PLASTIC, D2PAK-5ħ.5A SWITCHING REGULATOR, 63kHz SWITCHING FREQ-MAX, PSSO5 The Functional Equivalents tab will give you options that are likely to match the same function of LM2576-5.0WU, but it may not fit your design. The Form Fit Function (FFF) tab will give you the options that are more likely to serve as direct pin-to-pin alternates or drop-in parts. This table gives cross-reference parts and alternative options found for LM2576-5.0WU. Performance of LM2596įor a detailed performance review of the LM2596 see.
