    Hello, Could you tell me how to calculate Fco = 40kHz, Amid-band = 1.48, Fp1 = 25kHz and Fp2 = 100kHz? I don't know how to calculate Amid-band. Also I suspected that Fp1 = 40kHz and Fp2 = 160kHz if Fco = 40kHz Best Regards, Hidetoshi Matsunami

    The TPS51200 might better suit your needs. It has a lower input voltage range than the TPS51100. It is an LDO solution so you will need to check your average power dissipation and design the board accordingly to handle the heat rise in the part. …
