PN8044 ,Power Management IC, High-Efficiency Non-Isolated Buck Converter, 150-265V AC, DIP-8

The PN8044 is a high-efficiency non-isolated buck converter IC designed for auxiliary power supplies in offline applications. It integrates a 650V MOSFET and offers a wide input voltage range from 85V to 265V AC. With advanced protections such as Overload Protection (OLP), Overvoltage Protection (OVP), and Undervoltage Lockout (UVLO), the IC ensures safe and reliable operation.

Key Features:

• Integrated 650V power MOSFET for high voltage durability.
• Capable of delivering up to 4.5W at 230VAC in continuous mode.
• Optimized for reduced EMI and simplified compliance with global standards.
• Highly efficient, supports both buck and buck-boost operations.
• Undervoltage Lockout (UVLO) guarantees reliable startup under various conditions.
• DIP-8 packaging for ease of integration into small form-factor power systems.
