The 3A155D is a high-performance integrated circuit designed for efficient power management in various low-power AC/DC converters and power supply systems. Featuring an integrated power MOSFET and current mode PWM controller, this device simplifies circuit design by reducing the need for external components. The 3A155D automatically switches between normal PWM operation and burst oscillation mode under light load conditions, ensuring high power efficiency and low standby power consumption.

Designed with multiple safety mechanisms, the 3A155D offers comprehensive protection, including overcurrent protection (OCP), overload protection (OLP), overvoltage protection (OVP), and thermal shutdown (TSD), making it ideal for reliable and durable power supply solutions. The soft start function helps prevent sudden high inrush currents, ensuring smooth startup without stressing the components. Its compact DIP-8 package makes it easy to integrate into various circuit designs.

This versatile IC is suitable for a wide range of applications, including low-power adapters, auxiliary power supplies, and other switched-mode power supplies (SMPS). Its high power efficiency, safety features, and compact design make the 3A155D an excellent choice for engineers and designers looking to build efficient and reliable power systems.
