Application note
30 W AC-DC adapter with the L6565
quasi-resonant PWM controller

Introduction
This application note describes the evaluation board of the Quasi-resonant (QR) PWM
controller L6565 (order code: STEVAL-ISC001V1 - previous code EVAL6565N) and
presents the results of its bench evaluation. The board implements a 30 W, single-output
(15 V/2 A), wide-range mains input, QR converter that can be used as a reference design for
an AC-DC adapter, where good perf
