Other Parts Discussed in Thread: TPS40210 , TPS43060 , LM5122 I'm using TPS40210 to boost 24V to 58V, but the load is purely capacitive, a 8100uF 100V capacitor. The application is about pulsing a very strong pulse to a coil.
The circuit works very…
Hi Thomas,
I expect you will be able to get it to work with a lower value inductor too. I have 2 thoughts of what could be happening.
1. The extra parasitics from building it on a breadboard is hurting the accuracy of your over current sense point…
In slyt424, L1, Q1 and D1 were sized for certain maximum current level. You would need to ensure that those components are rated high enough for your application. The TPS40210 is a generic boost converter that has equations and tools to help you size…

Other Parts Discussed in Thread: TPS40210 Have designed TPS40210 to boost to 24 v 4A from 8-15v Vin 5A using switch pro online. The output voltage drops when the load goes above 400mA. Any idea why?
thanks,
Yes, the bq200T can charge a 20 cell nickel pack. What is your input voltage? You will need an input at least 20 * 1.7V = 34V to fully charge this pack. If your input voltage is not that high, you will need to boost it with the TPS40210.
I'm not sure…
Part Number: TPS40210 Hi Sir,
The customer is using the TPS40210 as a boost circuit(V-in=5V, V-out=48V, I-out 400mA). The MOSFET over heating is derived from the customer changed the MOSFET from AOS / AOD2544 to CYStek / MTB050N15BRJ3. When the boost…

I designed and built this circuit and did not work at more than 500mA(voltage drop 5-6V) with an inductor(4,7uH at 10A), diode DPG60IM400QB(400V, 60A) and 450kHz switching frequency. At higher currents(>500mA) the mosfet(no heatsink) is smoking in aprox…
