Hello, I am using TPS5420 to convert 12VDC at 3.6VDC 2A. With them food a GSM modem (Sierra Wireless Q26RD). I connected the circuit suggested by the simulator SitcherPro. I wired the circuit to test it manually. The output voltage is correct (3.58V). The problem is that after a few seconds to start the modem the voltage collapses. It seems like he could not provide strong enough. Modem consumption than 2A. It is not the appropriate component for any reason?
thank you very much
