LMZM23601: Prototyping, Lead Times, and Regulation

Thomas Kisylia

Part Number: LMZM23601

My team and I used WEBENCH to design a power supply circuit that has a 28 V input and is regulating down to 15 V. This supply will then be regulated down to 12 V, 5 V, and possibly 3 V. When looking at the recommended parts, it can be seen that the LMZM23601 is a "prototype." What exactly does this mean? How does it affect the quality of the part and will it affect the lead time? Additionally, does WEBENCH create a circuit that is automatically regulated (i.e. puts out a clean signal)?

    Hi Thomas,

    The LMZM23601 currently is in APL(advanced product launch) for early engagement so customer can evaluate the part well before full release around the April timeframe. Because of this LMZM23601 is considered prototype part. Since the LMZM23601 is a 1A current rated 36V buck converter that can output up to 15V, this device will fix your application.

    WEBENCH creates recommended circuit topology based on simulation. The results are close to experimental testing and should provide guidance for designing a well regulated design.

    So does this mean that if ordered today, it will get here in April?

    Hi Thomas,

    Currently there are prototype IC available for sampling on TI.com. The topmark for the device will be "PLMZM23601" and be ordered now and received immediately. Around April timeframe the part will go through full release and the topmark for the device will be "LMZM23601" showing that it is no longer a prototype part.

    So to answer your question, if you order the prototype LMZM23601 now, you will get the part within a weeks timeframe.

    Regards,
