Part Number: UCC28C41 Other Parts Discussed in Thread: TLV431A , TL431 Hi,
My customer used UCC28C41 to design a flyback with 3.3V/100mA for MUC VCC, they disable the 15V output circuit for the test.
I refer to the spec for voltage mode setup to add 2N222…
Other Parts Discussed in Thread: TLV431A
Hello
I have something wrong with TLV431A；
I use it as the reference voltage IC to a DDR IC, and have a filter capacitor of 0,1uF/16V 0402 between GND and pin 1(REF), our package is SOT-23-3
In that case ,there is…
Part Number: XTR305 Other Parts Discussed in Thread: TLV431 , TIDA-01633 , TLV431A Dear experts,
I designed a circuit to have an analog voltage output (+-10V) and I used the XTR305 with PWM control mode (PWM is set from uC). I followed design rules from …
Other Parts Discussed in Thread: TLV431A , TPS61070 I am currently designing a battery management system and need to get the voltage off of the battery cells so it can be compared in a microcontroller. I am trying to use the TLV431A to set a 3.7 V reference…
Part Number: LM431 Other Parts Discussed in Thread: TLV431A , TL431 , Hi Experts:
i designed a reference voltage for the signal detection with LM431B , the schematic is below:
Because the Cload selection could affect the Vout oscillation , i choose the…
Part Number: TPS23756 Other Parts Discussed in Thread: TLV431A , , PMP40514 Could you please help customer to check the POE circuit.
Currently the output is zero to GND.
Hope for your PCB review and solution.
have a nice day.
Thanks Ian,
Understood. Am using the A2 version for 5V high side sensing. Also found the 500K Ref impedance buried in the text description. Would be useful if that was listed in the specifications.
I settled on a TLV431A low power shunt reg with minimized…
Hi Vincent,
1. The voltage reference on the secondary side (D27) should be TLV431A (the low voltage variant)***
2. How come you change the R9 resistor from 1k to 100ohm?
Regards,
Tom A.
