Part Number: LM3423-Q1 Other Parts Discussed in Thread: LM3423 Dear TI,
We are going to build DRL with the LM3423-Q1.
We some question about LM3423-Q1.
1. What is the input / output tolerance rate? 2. ERROR AMPLIFIER: Under what conditions does the malfunction…
Part Number: LM3423-Q1 Dear TI,
For IC output characteristics Gain and phase margin should be measured in the operating area to satisfy the following requirements.
How do you measure?
Part Number: LM3423-Q1 Other Parts Discussed in Thread: LM3423 Dear TI Team,
Would you help this request?
I would like to know about the error range of Vout for the LM3423-Q1 product.
If the answer is difficult, is there a formula that can determine the…
Part Number: LM3423 Dear all,
I am using the LM3423 buck-boost evaluation board for testing a design. Ouput current goes unstable as Vin approaches the upper part of the range.
Vin: 7 V to 31 V Vout: 10.5 V Iout: 0.25 A PWM is to be used for dimming
At input…
