Hi
I build a Switching power supply based on PQ1CG2032. (Like fig 15 in https://www.electro-tech-online.com/custompdfs/2008/05/pq1cg2032_e.pdf )
It is working fine but the PQ1CG2032 becomes hot.
Then I saw a way to boost the output current capability for a linear regulator by using a PNP Darlington transistor in this article Silicon Chip Online - Low-Voltage Adjustable Regulator .
Now my question is. Can this technique also be used to boost the output current capability for a switching power supply?
