We have a requirement where we want to generate 4V @ 3A supply. 4V supply is required to power GPRS modem, 1.6A is peak current requirement. We want to have a supply that can source 3A to cover for any losses.
Our device has 36V input which will be connect with LMR14050 to generate a 5V @ 5A supply.
Design requirements for TPS54302:
Vin: 5V 5A
Vout: 4V 3A
We are concerned if TPS54302 is right product for a low a drop-out voltage of 1V.
As per datasheet:
7.3.10
To improve drop out, the TPS54302 is designed to operate at 100% duty cycle as long as the BOOT to SW pin voltage is greater than 2.1 V typically.
It will be great if some body can guide us if we are looking at right product.
