LM5150-Q1: LM25150-q1 replaces LM5150-q1

Part Number: LM5150-Q1
Other Parts Discussed in Thread: LM25150-Q1

Hi Expert,

Our customer wants to use LM25150-Q1 to replace LM5150-Q1. Currently they want pin2pin replace. 

For LM5150-q1, they current apply a sync signal on PIN1 from MCU. Whereas, LM25150-q1 PIN1 is GND. They want to check whether PIN1 is connected internally to GND. If it's not, the replacing might be possible. But if YES, the MCU may be damaged when it output a positive voltage.

Thanks and Best Regards

Elec Cheng
