  • RE: TLV61046A: TLV61046A is P2P with LTC3400 & efficiency

    Hi Alex, ILTC3400 can't output 250mA when Vin = 1.8V, Vout = 5V. The max Iout is around 150mA. There is no device that p2p with LTC3400 and better efficiency. TLV61070A and TLV61220 are the most close devices, although they are not p2p. Regards Lei …
