Other Parts Discussed in Thread: PMP7966,
I have been asked to design a boost converter that has the following attributes:
Vin= MIN 5.25V, MAX 16V; (PREFERABLY WORKING AT LOWER INPUT VOLTAGES FROM 4S LI-ION BATTERIES IN SERIES/PARALLEL.)
Vout = MIN 46V, MAX 52V @2A. NOMINALLY 48V@ 2a , 96W.
I noticed that your PMP7966 POWER SOLUTION FOR AN AUTOMOTIVE FUEL INJECTOR reference design may work under these conditions. It doesn't appear that you offer a demo circuit for this part and PSPICE won't run for lack of a simple SPICE library part (CD4017BM96).
WEBDESIGN2 did produce a simulation based on 1 chip and 1 inductor however the inductor was too big for the allotted real estate.
Design requirements call for the boost converter to run for 30 seconds cycles followed by a long (hours) rest period so I thought I could run the PMP7966 configuration on 2 channels instead of 4 to reduce the board's footprint.
Is this viable?
Can you suggest another chip that actually has a demo board I can test?
Time is of the essence.
