GENERAL DESCRIPTION

OB2353 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 10W range.

OB2353 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).

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.

OB2353 is offered in SOP8 package.
