Part Number: TPS40090 The schematic designed by 4 channel，my issue is the load current only 80A，can't reached 120A，Please help confirm whether RC (CSX) is reasonable,the resistor value is 3.48Kohm .The inductance value of the inductor is 0.22uH,and DCR…
Part Number: TPS40090 Other Parts Discussed in Thread: TPS40091 Hi Team,
Can you please share what is the expected TPS40090 powerdown timing when EN is pulled low? Should the converter stop switching immediately, or is it dependent on the BP5 discharging…
Part Number: TPS40090-Q1 Does this chip has the following functions:
1. Short circuit protection;
2. Slope compensation;
3. I use external housekeeping 12V to power the IC. Can it be Used in High Voltage application (Vin = 100V; Vout = 24V; Pout…
Part Number: TPS40090 Hello,
I would like to ask about peak current mode control of TPS40090. Current sensing pin 1 until 4 is compared to the control current (Idroop) provided by the voltage loop regulator. I don't really understand this, how do Idroop…
Part Number: TPS40090
Hello,
1. I'm trying to understand the formula for setting up the switching frequency of TPS40090. How did the formula has the 39.2x10^3 and why fph need to power up by -1.024?
2. Is TPS40090 able to work on single phase…
Part Number: TPS40090 Tool/software: WEBENCH® Design Tools Hello,
I'm trying to understand the DC current sensing of the TPS40090 steady state simulation. According to the reading material when RDCR and CDCR are selected in such a way that the RC time…
Part Number: TPS40090 HI Team,
I have a couple of questions
I’m having a look at the implications of using the TPS40090. Please could you clarify the relationship between “Phase frequency set range … min 100 kHz, max 1200 kHz”, and “Synchronisation…
Part Number: TPS40090 Other Parts Discussed in Thread: TPS40422 , TPS40428 , TPS40322 , This is for a 0.85 V, 40 A supply (i.e. up to 10 A per phase).
Minimum current sense voltage (inductor DCR)
I’m using inductor DCR sensing, and of course…
Part Number: TPS40090 Hi All,
I'm designing a buck converter using TPS40090 as the controller. This buck converter need to be a programmable one which means that i can control the output voltage based on the program voltage. This IC has a internal 0…
