Part Number: UCC38086 Hi,
I have used ti webench to design a 100w push-pull. But, when I load 0.25 A, the input current is gradually increasing and my 4A power supply is going to CC mode. When I checked the gate waveform, the duty cycle is 50% at 0…
Part Number: UCC38086 Other Parts Discussed in Thread: TL431 , TLV431 Hi,
I have used TI webench to design a pushpull converter using UCC38086. As per the datasheet of UCC38086, the max duty cycle is 50%, but the webbench design shows the duty cycle…
Part Number: UCC38086 Hi,
I have used UC38086 pwm controller to design a pushpull conveter. While doing the short circuit test, the ic is not going to hiccup mode and input power is taking on output short circuit. Can you suggest a soultion?

Part Number: UCC38086 Hi,
I have used webench tool to design a pushpull converter. Attached the design file. I am not able to get details of transformer design. Can you please support me to select suitable transformer core & design. WBDesign18.pd…
Hi Hunag,
Thanks for the explanation. As per the datasheet of UCC38086 , the max duty cycle is 50%, but the webbench design shows the duty cycle as 90%. In the webench, I am not able to update the duty cycle information to change the design. Hope…
Part Number: UCC38086 Hello.
I'm looking for an example of forward boost converter based on push-pull method.
Does TI give me some specific application note which explains PWM duty and its usage for boost up ?
So far I have seen buck converters…
Other Parts Discussed in Thread: UCC38086 , TL431 I'm working on a consumer product which looks like a perfect fit for a UCC38086. Summing a sloping compensation current to the current signal filter looks like an excellent idea. I'm eager to try it but…
Hi illia and Katlynne,
Thank you for the swift reply.
I have further inquiry;
1) The supply voltage of the proposed digpot IC is 2.7 - 5.5V. I need digpot IC that operates on 1.8V - 5.5V to allow me to supply 1.8V- 2V maximum to the IC, this…
