Manufacturer: On-Bright

Overview: OB2353 Low Power Off Line SMPS Switcher Freq Shuffling GENERAL.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

OB2353 bines a dedicated current mode PWM controller with integrated high voltage power MOSFET .It is optimized for high performance low standby power and cost effective offline flyback converter applications in sub 10W range.

OB2353 PWM frequency operates in the fixed and trimmed .

At no load or light load the frequency is internal adjusted, the IC operates in Extended ‘burst mode’ to minimize switching loss.

Key Features

  • Optimized for sub 10W.
