Since its conception, the KA5H0380RYDTU has been a mainstay of Power Management ICs (PMICs). With a maximum output current of 800mA and a direct conversion from AC to DC, this little power converter is big on performance. This article explores the application field and working principle of the KA5H0380RYDTU.

The KA5H0380RYDTU was designed to be used in AC/DC converter and offline switcher applications. With a maximum output current of 800mA, the KA5H0380RYDTU is able to provide up to 3.6 Watts of power. The maximum input voltage range of the KA5H0380RYDTU is 110V and it has an efficiency of up to 86%. This makes it ideal for use in applications which require a reliable, efficient, and cost-effective power supply.

The KA5H0380RYDTU is a synchronous rectified, zero-voltage transition (ZVT) flyback converter. It is capable of providing a wide output voltage range from 5V to 36V. The output voltage can be adjusted via an external voltage divider. This allows for a wide range of applications and flexibility.

The working principle of the KA5H0380RYDTU is based on a ZVT flyback topology. This technology works by converting AC power to DC power by first rectifying the input AC voltage, then DC-DC converting the voltage for a specified output. This is accomplished by utilizing a transformer, two MOSFETs, and two capacitors. The transformer transfers the energy from the input voltage to the output voltage. The two MOSFETs control the flow of current and the two capacitors store energy. The output voltage is regulated by an external voltage divider.
