The KA5M0380RYDTU is a high-performance power management IC designed for advanced switching power supply applications. Manufactured by Samsung Electro-Mechanics, this device integrates a robust MOSFET and PWM controller in a single package, enabling efficient voltage regulation and power conversion. With its low RDS(on) and high switching speed, the KA5M0380RYDTU is optimized for applications requiring minimal power loss and high thermal stability, such as server power supplies, industrial equipment, and telecom systems.
Featuring a synchronous rectification architecture, the KA5M0380RYDTU enhances efficiency by reducing diode conduction losses, making it ideal for high-current, low-voltage applications. The chip supports a wide input voltage range (typically 4.5V to 23V) and delivers an adjustable output current of up to 5A, ensuring flexibility in diverse power supply designs. Its integrated protection mechanisms, including overcurrent, overtemperature, and undervoltage lockout (UVLO), safeguard the system against potential failures, enhancing reliability in demanding environments.
The KA5M0380RYDTU employs advanced process technology to achieve high power density and thermal performance. Its compact DFN-8 (3mm x 3mm) package minimizes board footprint while improving heat dissipation, making it suitable for space-constrained designs. The device operates with a low quiescent current, reducing standby power consumption and meeting energy efficiency standards such as Energy Star and 80 PLUS. Additionally, its low noise and electromagnetic interference (EMI) characteristics simplify compliance with regulatory requirements.
