  • RE: TPS62745: Iq at room temp(25C)

    Max Fujimoto

    Hi Colin, When voltage is applied to the VIN and EN pins, should we assume that 100 nA flows to VIN and 50 nA flows to EN due to input bias current, for a total of 550 nA together with Iq (400nA as you mentioned)? Regards, Max

    Hi Kyohei, Can you please share the input voltage range requirement? You mention 3.3V to 7V above - is that incorrect? If its indeed 3.3V to 7V then why do you mention TPS62745 does not meet Vin specs when it supports 3.3V to 10V? Regards, Gautam
