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

    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

  • RE: TPS62745: Regarding DC-DC converters with high efficiency at low current

    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

  • RE: TPS62745: Not working properly in constant current source (Both in with load and without load conditions)

    Hi Aswin, Could you use the external source with enough capabilities to supply power to TPS62745 ? Thanks, Colin
