Part Number: TPS40091 Tool/software: Dear Team,
Do you have parts that can replace MP29001?
A cross-reference search couldn't yield any part numbers.

Hi Sergej,
Although I am not convinced why you would need a Type III compensation instead of Type II, you can disable droop function by shorting pin 7 (DROOP) and 8 (REF).

Other Parts Discussed in Thread: TPS40090 Hello, in the datasheet of TPS40090/1 there are three proposed methods of sensing the inductor currents: Resistive, DCR and thermally-compensated DCR. My problem is that I can not use any of these methods in my…
Other Parts Discussed in Thread: TPS40090 , TPS40091 Hello,
I have a question about the tps40090 datasheet. On the page 15, there is the Modulator bode diagram. I would like to know what is the modulator system. Is it the inductor, capacitor and Rout…

Hi Qian,
Just to confirm, my customer sees on the PWM a 2.3us delay followed by what seems like high impedance (they are testing the controller by itself). If they add a load, it goes to 0V after the 2.3us delay. Is this the expected behavior from the…

At this voltage and power level we recommend one of our active clamp forward controllers like UCC2897A. http://www.ti.com/tool/PMP8861 is an example design that is close to your design target. Please note that at 1.2V output is below the range…
Hello Yaita, What amount of current do you need to support? Have you looked at the TPS53667, TPS53647, or TPS40091? The TPS546x7 solution should be capable of supporting between 240A - 420A. I would also recommend looking at the following TI Designs:…
Andy,
For 50 A load current you will probably need a controller. There are 6 possibilities:
TPS53667 - 6-Phase, D-CAP+ Step-Down Driverless Buck Controller with NVM and PMBus Interface for AVS www.ti.com/.../tps53667
TPS53647 - 4-Phase, D-CAP…
Other Parts Discussed in Thread: TPS40091 , TPS40140 Hi,
I am looking for a controller chip for use in a large (>1000A) buck controller driving a IGBT at 15kHz. Any suggestions?
Bill
