AP2358
AC-DC PWM CONTROLLER
CURRENT MODE PWM POWER SWITCH FREQ SHUFFLING
REV1.0

DESCRIPTION
FEATURES
AP2358 combines a dedicated current mode PWM
controller with a high voltage power MOSFET. It is
optimized for high performance, low standby power,
and cost effective off-line flyback converter
applications in sub 15W range.
AP2358 offers complete protection coverage with
automatic
self-recovery
feature
including
Cycle-by-Cycle current limiting (OCP), over load
protection (OLP), VDD over voltage clamp and
under voltage lockout (UVLO). Excellent EMI
performance is achieved with proprietary frequency
shuffling technique together with soft switching
control at the totem pole gate drive output.
The tone energy at below 20kHz is minimized in the
design and audio noise is eliminated during
operation.
The AP2358 is available in DIP7 package.
