Description

OB2353 Low Power Off Line SMPS Switcher

OB2353 Low Power SMPS Switcher for sub 10W applications with integrated 650V MOSFET and soft start feature.

The OB2353 Low Power Off Line SMPS Switcher integrates a high voltage power MOSFET optimized for sub 10W applications. This device features a fixed 50kHz PWM frequency and operates in an extended burst mode, effectively reducing standby power and enhancing efficiency. The OB2353 ensures reliable power startup with low VDD startup current and offers automatic self-recovery protection features, including cycle-by-cycle current limiting and overload protection.

Incorporating advanced techniques like frequency shuffling, the OB2353 Low Power Off Line SMPS Switcher minimizes EMI and audio noise during operation. Its leading-edge blanking on the current sense input reduces component count and system cost, making it an excellent choice for applications like battery chargers, power adapters, and digital cameras. With its compact SOP-8 package, the OB2353 is designed to meet the demands of modern electronic devices.

Ideal for offline AC/DC flyback converters, the OB2353 Low Power Off Line SMPS Switcher is a reliable solution for various applications, including set-top box power supplies and open-frame SMPS designs, ensuring high performance and efficiency in every scenario.
