Diodes Incorporated AP3927D 700V Non-Isolated Regulator

Diodes Incorporated AP3927D 700V Non-Isolated Regulator features low standby power and is ideal for IoT applications and home appliances using non-isolated buck or buck-boost solutions. This Diodes Incorporated AP3927D monolithic device combines a controller and a 700V high-performance MOSFET, requiring minimal external components and providing a low BOM cost. It operates in fixed-frequency CCM mode under heavy loads and switches to PFM mode for light loads, ensuring quiet, noise-free performance at low peak currents. The AP3927D offers multiple protection features for enhanced safety and reliability, including overtemperature protection, undervoltage lockout, output short protection, and overload protection.
