Part Number: UCC20225-Q1 Other Parts Discussed in Thread: UCC20225 , TPS2838 Tool/software: Hi,
I want to use UCC20225 gate driver for the synchronous buck design. The design is 10:1 ratio. If the PWM duty cycle as input to the UCC20225, is 10%, would…
Part Number: UCC20225-Q1 Hi team，
The customer wants to know how to calculate the capacitance CVDD of Channel B? In the datasheet, there is only a text description suggesting a value of 10uf.
Is there a more detailed calculation method available for customer…
Part Number: UCC20225-Q1 Other Parts Discussed in Thread: UCC20225 Dear Sir/ Madame,
I intend to use UCC20225 in some of our application, but I had a special requirement to control the dead time (DT) with a microcontroller.
The dead time is usually set…
Part Number: UCC20225A-Q1 Other Parts Discussed in Thread: TINA-TI I am simulating a Class-D amplifier circuit. When i simulate it part by part , i get the proper simulation results but when i integrate the complete chain, i am getting convergence issues…
Part Number: UCC20225-Q1 Hello,
In data sheets write that the VDDA\B -VSSA\B (dual) component pin voltage-ground respectively can be between -0.3 and 30 volts. Is it possible to flood the output ports (for example: VSSA = -54Volt and VDDA = -49Volt, so…
Part Number: UCC20225-Q1 Hi team,
Is UCC20225-Q1 only for 48V system?
Datasheet says it is suitable for 48V application. On the other hand, datasheets also says channel to channel voltage allows upto 700V. Is it OK to use this device for HV system, such…
Part Number: LM5155-Q1 Other Parts Discussed in Thread: UCC20225 , LM5155 Hi team,
1 . Customer can’t find the calculation of R UVLOS and C UVLO, can you please show me how to calculate them .
2.Could you please send me the internal resistance of Gate…
Hi Alina,
Sorry, I should have included my source for the image. It is from the UCC20225-Q1 datasheet in this case:
There are some other options shown in this datasheet as well. It is for an isolated driver, but these solutions should work just as well…
Part Number: UCC20225A-Q1 Other Parts Discussed in Thread: UCC21551 , UCC20225 , UCC21225A Hello:
It seems that nowhere in the ds of UCC20225A is any mention of ratings of the VSSA pin which gets connected to the half-bridge node named SW.
Is it limited…
Part Number: UCC21222-Q1 Other Parts Discussed in Thread: UCC21540-Q1 , , UCC21520-Q1 , UCC20225-Q1
Hey Team,
I have a customer that is deciding between the UCC21222-Q1, UCC21520-Q1, and UCC21540-Q1 for a Belt Start Generator (BSG) automotive application. …
