Modifications

The SR036DB1 may be modified to provide higher output current. Remove Q1 and replace with a D-Pak N-channel MOSFET with

a voltage rating appropriate for the input voltage. The on resistance of the replacement FET is not as important as the gate

threshold voltage – the lower the threshold voltage, the more efficient the converter.

To reduce ripple at the higher output current, C1 may be replaced with a higher value capacitor.
