Part Number: FLYBUCK-FLYBACK-DESIGN-CALC Hi,
On the flyback topology (working in DCM), There are two types of ringing/ oscillations observed across the drain to source of switching FET.
Please see marked regions A and B. What is the root cause for these…
Part Number: LM5141DESIGN-CALC Other Parts Discussed in Thread: LM5141 The design tools I believe maybe incorrect. According to the latest rev.D datasheet page 16 equation 4 is states:
However in the Design Tool provided Rfb1 and Rfb2 are swapped. Shown…
Part Number: LM5069QUICK-CALC Other Parts Discussed in Thread: LM5069 Hi Expert,
The customer is considering the LM5069 for below conditions.
Two input sources to support the output capacitance (3000uF) and loading is 3KW.
The input range is 36V~72V.

I would like to design the isolated flyback circuit using TPS61175 based on the following system requirement.
Input Voltage = 5V
Output Voltage = 12V
Part Number: UCC28740 Hello Guys,
Our customer is having trouble calculating the gate resistance for a n-mosfet driver. He is driving an n-mosfet with a gate voltage of 14v and he need to know the external gate resistor he should use.
He is thinking…
Part Number: WEBENCH-POWER-DESIGNER Other Parts Discussed in Thread: LM5156 , LM51561 , LM5156-Q1 , LM51561-Q1 Hi support team,
LM5156 and LM51561 do not support WEBENCH Flyback. Do you have any plans to support it in the future?
I substitute LM5156-Q1 and…
Other Parts Discussed in Thread: UCC28881 Hi!. I`m Eugenio Mercol from Argentina.
I`m developer and I need support about devices to design a 220VCa to 3.3VCC 300mA power supply without transformer or flyback.
Will be used like power supply for a Domotic…
Part Number: TPS25740 Other Parts Discussed in Thread: TPS25750 , PMP11451 , TPS65987D Hi
I am found the simple flyback with the PD3.0 solution and share it with my customer, and I found the TPS25740 is an easy PD IC, but it is NRND.
May I change the following…
Apologies the reference design number should have been PMP8803.
The TPS23734 reference designs that the team has today are catered towards the Class 4 (25W) space so unfortunately I don't have a reference design to recommend that is optimized…
