Hi Andy,
You will need individual isolated supplies for each channel, since they need to be referenced to the source of the high-side FET. The source of the high-side FET will go between VBus and Vload, depending on if the FET is on or off. I recommend…
Part Number: SN6505B Other Parts Discussed in Thread: TIDA-01159 Hi Sir
May I know SN6505B have reference design include transformer p/n for 5Vin to +/-12Vout?
Thanks
Hi Andy,
Even if these modules are isolated, I do not see a CMTI (common mode transient immunity) rating. I would suggest following one of our reference designs to create a high-voltage half-bridge circuit, such as http://www.ti.com/tool/TIDA-01159 .

Part Number: TIDA-00951 Hello,
we would like to build TIDA-00951 system (as we can not buy it). System consists from other reference designs, if possible we would like to order/buy those not to deal with their assembly. Could you write back whether following…
Hello Derek, Thank you for the quick response. I am looking into the reference design and it seems like this is what I need. I am just wondering if this design can be extended to accommodate for a full bridge design? Would I simply need to copy this over…
Capture above represents two overlapping PWM signals and the ensuing 240 output. They are not complementary paired PWM used in TIDA-01141 with TIDA-01159 isolated gate driver inverter. Complementary PWM seemingly does not produce the same peak inductor currents…
Part Number: UCC21520 Other Parts Discussed in Thread: TIDA-01159
Hi, everyone,
I would like to use the UCC21520 isolated gate driver to operate as shown below.
However, I can not control the high-side mos-fet because bootstrap does not work. Please…
Hello Bob,
There is a solution for the high side floating MOSFET drive in DC applications. Since the operation needs to be DC there will need to be a dedicated floating bias supply for the HB-HS high side bias. There is a TI design which features the…
