Part Number: UC1901 Other Parts Discussed in Thread: UC3845 Hi Team
good day!
Customer have some question:
There are three questions when uc1901 is used in isolate feedback: 1. What is the relationship between driver output drivA / B and comp or inv of…
Part Number: UC1901 Hi,
I was recently trying to delve deeper into understanding the working of the UC1901 IC and wanted to verify the frequency response of the error amplifier and the demodulation stage.
To do this, without using a complete converter…
Part Number: UC1901-SP Other Parts Discussed in Thread: UC1843-SP ,
Hi,
I am designing a DC-DC fly-back converter using UC1843-SP PWM controller for space application. The use of Opto-coupler is prohibited in my application hence feedback control is done with…
Part Number: UC1901-SP Other Parts Discussed in Thread: TIDA-070002 , UC1843A-SP , Team,
My immediate need is to come up with an architecture for a HARD Isolated House-Keeping power supply (~50W).
Similar to TIDA-070002
The PWM Controller’s (UC1843A-SP…
Part Number: UC1901 Hi,
We are using UC1901 devices to provide isolated feedback. There have been instances where the feedback for the voltage (resistor divider network from output voltage) cannot be trimmed. Circuit functionality was restored after replacement…
Part Number: UC1901 What is the plating of UC1901L terminals, materials and thickness of each layer of plating ?
It is defined POST-PLATE in datasheet. What does it mean ?
Part Number: TPS7H5001-SP Other Parts Discussed in Thread: UC1901 Hello,
I m trying isolated active clamp forward DCDC converter PWM Controller TPS7H5001 in primary side of Converter and output feedback through UC1901 feedback generator but output…
Part Number: UC1901 Other Parts Discussed in Thread: UC1843 Team,
The idea is to use UC1843 as PWM controller and UCx901 for feedback using a transformer:
-Do we have some more precise information to dimension/choose the transformer? Page 4 gives some information…
Antonio,
Since it doesn't contain a driver OUT stage like a PWM controller, I anticipate the expected power dissipated in UC2901 is very low. As far as "cooling", I've seen similar LCC packages cooled using thermally conductive epoxy over the perimeter…
