Part Number: LM25037-Q1 Other Parts Discussed in Thread: LM25037 Hello,
I designed a push-pull converter using LM25037. Currently the converter is working without any problems. However, at nominal operating values, system efficiency is 85%. I want to…
Part Number: LM25037 Tool/software: Hello:
Excuse me for tricking the system: I got in here by following customer help link...but you cannot pass this gate unless I put a part #...
So after a short while, I got the approval to download PSPICETI. …
Part Number: LM25037 Tool/software: I’m designing a 12V–360V push-pull converter using the LM25037. The primary current is measured with a current transformer. Should the sense resistor be placed close to the CT transformer or close to the LM25037? Currently…
Part Number: LM25037 Other Parts Discussed in Thread: TL431 How to design the FB and Comp for isolated DCDC? All the reference design that from TI is connect output devided voltage to FB directly. But it doesn't work for isolated DCDC. Can we use below…
Part Number: LM25037 Tool/software: Hi,
I’m designing the UVLO circuit for the LM25037 and I don’t understand the 20×10⁻³ term (20mV?) in Equation (7) used to calculate R1. Is this perhaps the comparator’s internal hysteresis that isn’t explicitly mentioned…
Part Number: LM25037 Other Parts Discussed in Thread: , UCC2808A-2 Tool/software: Hello Team,
I am looking for and DCDC controller for following application:
Input voltage: From Battery ~7V
Output voltage: Configurable to 250V and 420V
Output…
Part Number: LM25037 I'm designing an application in where the LM25037 driver chip is used. This chip is connected to a DC input voltage wrt a DC PGND (hereafter, PGND). I'm using a 1-meter power cord between by DC source (A beefy PSU) and my PCB using…
Part Number: LM25037 Tool/software: Hi,
I designed a 12V – 360V push-pull converter. At the very first startup, the circuit did not start. The hiccup mode was activated and got stuck in it. I had not connected a capacitor to the RES pin, so the CBC…
Part Number: LM25037 Other Parts Discussed in Thread: TL431 Tool/software: I would like to control the COMP input with an optocoupler, but I want to decrease the internal 5kΩ resistor. Would it be sufficient to connect a resistor between COMP and 5VREF…
Part Number: LM25037 Tool/software: Hi,
I’m designing a 12 V to 360 V push-pull converter with an LM25037. The maximum output current is 1.2 A. The output inductance is 3.6 mH and the output capacitance is 68 µF. My question is: how can I determine…
