Part Number: LM3475 I was wondering if this buck converter can be configured to generate a negative output voltage. This is often achieved by connecting the converter’s output to the system ground and using its ground pin as the negative output. Has anyone…
Part Number: LM3475 Other Parts Discussed in Thread: LM3485 Hello.
I am the developer of the TI-PMLK series for TI, and now I am using the TI-PMLK BUCK to validate an analytical model predicting the value of the switching frequency of hysteretic regulators…
Part Number: LM3475 Other Parts Discussed in Thread: LM3485 Hi,
I've been asked to simulate a customer's design which uses the LM3475 Hysteretic SMPS. I would like to determine, among other things: power supply efficiency, output voltage ripple, and…
Part Number: LM3475 Hi Team,
For input voltage higher than 12V (maybe up to 100V), if I use resister divider, Zener and TVS for Vin pin and EN pin, make it below 10V, is this worked?
Thank you very much!
C.T.
Part Number: LM3475 Other Parts Discussed in Thread: LM5117 , LM3423-Q1 I want to build a constant current circuit with constant load current of 0.5A, the load impedance is varied from 10~100ohm (which means the output voltage should be adjusted from…
Part Number: LM3475 Hi,
I am using lm3475 for the battery charger circuit.V ref value for the hysteric comparator is 0.8V. but in my case voltage at feedback pin is 1.1V still IC does not try to maintain it at 0.8V. So output is coming more than expected…
Manali,
Most likely the issue is the 47 uF ceramic output capacitor. LM3475 is a hysteretic converter. It relies on significant ripple content on the output. Try removing that capacitor.
Part Number: LM3475 Hi there,
when i tested the pmlk with lm3475 on it, i didn't see any over/undershoot in SW node.
Would you mind tell me the reason? Because of the slow ramp up or shut down rate of Q1, or something else.
I was told the leading…
