Part Number: PMP3034 Hi, AE Team:
Recently, I am reading the reference design of PMP3034. The selected value of inductor L1 is not compatible with the one in Power Stage designer's analysis( Inverting Buck-Boost ).
It seems that the design and analysis…
Hi Iven, Hi Orlando,
thanks on your feedback. Further questions would be regarding the component sizing. Topic 1: Due to space constraints on PCB we would like to use as smallest packages as possible for MOSFET, Diode and Inductor. Parts used in PMP3034…
Yong,
The RTN pin and all the connections to ground in the application schematic are connected to -Vout in the inverting buck-boost topology. The VOUT terminal of the application schematic is connected to ground (negative terminal) of the input supply…
Hello Elsa,
For 5.5V to -3V, LMR70503 would be the smallest solution we have available as far as I know. The device is WCSP, sometimes customer do not like this package.
For the negative converter, a flyback design is a possibility. Please have a look…
