Hello, is it possible to generate two negative (-5V, -10V) voltages with the MP1530 ?
by using the VGH Part like the VGL Part in the D.S. (fig 3) ?
I need the voltages:
VGH 18V 8mA
VGL -10,5V 8mA
VSN -5,0V 26mA
VSP 5,0V 27mA
Hello @JFiebig,
As per the functional block diagram, the VGH pin is connected to p-channel MOSFET and the feedback threshold is Vref(positive) which is different from VGL configuration. The absolute maximum rating indicate the VGH voltage can be as low as -0.3 V. So it is not recommended to use the part beyond the maximum rating range.
