hi Sir

I survey the LTC3400 to do the circuit, also see TI have a TLV61046a, does they P2P?

and, may i know how the efficiency of TLV61046A in Vin 1.8V; Vout =5V/250mA

thanks

Hi Alex,

TLV61046A is p2p with LTC3400. But the max Iout of TLV61046A is around 160mA when Vin = 1.8V and Vout = 5V.

TLV61070 can output 250mA when Vin = 1.8V and Vout = 5V with efficiency > 85%. It's not p2p with TLV61046A.

I'll further check whether there are better p2p choices.

Regards

Hi Alex,

The efficiency is around 70% for TLV61046A when Vin = 1.8V, Vout = 5V, Iout = 160mA.

Hi Lei

TLV61046A efficiency less than ADI/LTC3400 in the same condition?

did you have other advise p2p with LTC3400, efficiency better?

thanks

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.
