Hi,
We designed a 22-30 V to 6V converter using the TPS54341, please note the schematic below. The inductor value is 3u3 and the voltage drop of the diode nominally is 0.55V.
The converter correctly outputs 6V under 4 Ohms of load (~1.5A). However on a 2 Ohms load (~3A) the voltage drops to 3.7V. Based on the design below do you know what might cause this issue?
