HI Sir,how do we define the switching frequency of the L7987the switching frequency range is between 250KHz and 1.5MHzlooks like if the switching frequency is set to 1.5MHz, the ripple appears to be much smaller, so can we set it to 1.5MHz under norm...

HI Sir，we have two different results of the ripple noisebase on same PCBA design, but different L7987 origin:1. Mark of "ST e3 G9207，L7987， CHN 3L0"，ripple noise 2.2V 2.9KHzinput 24V， output 12V， load 5ohm 2.4A 2. Mark of "ST e3 7B658， L7987， PHL 037...

HI Sir,we have applied L7987 and L7987L on our touch display computer,we don't have enough stock for nowis there any substitued parts availablethanks�?With best regards，PZ​
