Part Number: UCC28251 Other Parts Discussed in Thread: LM5036 , Hello,
I am trying to decide if symmetrically driven half bridge DC/DC PWM converters (such as using UCC28251 or LM5036) are suitable for wide output voltage range required in battery charging…
Part Number: UCC28251 Other Parts Discussed in Thread: LM5036 Hello,
Is UCC28251 the best choice for asymmetrically driving a half-bridge (as opposed to 50% duty cycle on both top and bottom switches) for an off-line converter with 400Vin to isolated…
Part Number: UCC28251 Hello everyone,
I would like to use a logic High or Low level to directly control wether the IC is enabled or disabled.
The Problem is, i am hesitant to use the EN-Pin for this because of its Pulse-enable-functionality. According…
Hi,
The UCC28250 datasheet makes this clear that this device min switching frequency typical 85kHz. So UCC28250 cannot work at 50kHz. You need to use UCC28251.
Please also take reference of this below application note. RT can set up UCC28C51 fsw to 27kHz…
Part Number: UCC28251 Other Parts Discussed in Thread: LM25037 , Hello Ti,
Is there an un-encrypted transient model available for the UCC28251 controller? Or is there a controller with similar features and characteristics available with a transient SPICE…
Part Number: UCC28251 Other Parts Discussed in Thread: UCC28250 Hi
I try to make a symmetrical half bridge converter using UCC28251.
If there's anything that can help you with this, please.
Thanks
Part Number: UCC28251 How to use secondary side control with UCC28251?
what is it meaning?
Is it controlling the secondary PWM duty cycle and make primary following the secondary ?
Part Number: UCC28251 Other Parts Discussed in Thread: UCC28951 Hi team,
It is nice to know you here. My customer has two questions about the UCC28251 RT function.
1. Is RT pin internal circuit a current source or voltage source? What is the voltage/current…
