Part Number: TPS40303 Hi Experts,
We are looking for the information at the TPS40303's HDRV and LDRV pin drivers.
If the device is designed to convert from 3.3V to 1.0Vout, can you share us the average DC level of these pins, and waveform? We are requesting…
Part Number: TPS40303 Hi team,
when using the TPS40303DRCR, the datasheet recommend using 100nF for bootstrap capacitor. if using 470nF or 220nF, will there be any risk?
Part Number: TPS40303 Other Parts Discussed in Thread: TPS40305 Dear TI team,
Good evening.
We have done webench simulation for 12V to 5V at 3A(TPS40303DRCR),which will be supporting maximum 15watt load.
We are now checking in PCB practically and facing…
Part Number: TPS40303TPS40303 team,
A customer designed a board with TPS40303 to support up to 21A load. The Overcurrent isn't expected to be a factor since it is programmed at about 55 to 60A with R = 15.4kOhm.
They tested first with current well…
Part Number: TPS40303 Other Parts Discussed in Thread: TPS40304 , TPS40305 Can customer connect TPS40303 BP to VDD=5V? The reason for the unusual request is we are trying to replace a competitors device in an existing application.
Regards, Mark
Part Number: TPS40303 Hi Team,
My customer reported an issue that BP PIN short to BOOT PIN while using the TPS40303, this issue happened especially doing the output short test:
Could you kindly help on below items?
1) Could you kindly share bootstrap…
Part Number: TPS40303 Hi Team,
My customer reported an issue that while the VDD drop and restored, the TPS40303 couldn’t provide normal output voltage.
The VDD provided by previous power module output which has the over current protection, if…
Part Number: TPS40303 Hello,
I need to generate a 0.9V from a 12V input (17A max) and the design is highly constraint in efficiency.
I did look at the recommended TI parts for Altera/Intel but I need an efficiency above 90%. Which I achieved with a TPS40303…
Hi Steven,
The only problem I notice on schematic is the compensation. TPS40322 is a voltage mode controller, type-III compensation is needed.
I'm not sure if the current imbalance is related to unstable loop.
Can you populate R624, C619 and C620…
Part Number: TPS40303 Could you help check above questions，tks！
1. pls help check whether TI can providethe internes Blockdiagramm for the LDRV / OC functions of Pin9 ？
2. Pls help check if the TPS40303's Pin8(SW) connect to GND，both Pin7(HDRV ) an…
