OB2354 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 20W range.
OB2354 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 On-Bright 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.
OB2354 is offered in DIP8 package.
