I have a trouble in designing power supply for my device. I've shifted 3.3V up to 5v by using LMR 62421 manufactured by Texas Instruments. I'm planning to use the 5v rail to power my devices(module, sensor, etc...) Everything is fine except that I can't find out how much load(output) current LMR62421 allows in maximum. Datasheet only says it has minimum switch current limit of 2.1A. I don't think this is equal to Maximun load current. There are some equations on datasheet but they start from knowing VIN VOUT Ioutmax. My devices which are connected to 5V rail will consume approximately 1.6A in sum. I expect that LMR 62421 will be fried if I do not take careful consideration on its maximum allowable current value. Can anyone help me find it out?
