Dear Sir,
I am using the PMP7579 circuit for 18W.
The Problems are
1. Frequent failure of capacitor - 1uF - C13. Due to that output current is low.
2. Failure of RC Snubber circuit - 11K, 22nF - C8 & R5. Due to that IC and Mosfet blow.
How to rectify or overcome from this problems.
Thanks
S.Rajasekaran
