The converter is also packaged in a TO-220 package and is RoHS compliant.

Application Field

The JCE0612D05 converter is versatile and suitable for a variety of low power applications. This converter is used in automotive, industrial, telecom, and consumer electronics applications. It is also applicable to LED lighting, digital camera, and portable device applications. It can also be used as a general purpose regulator in automotive electronics where the load current can be maintained over a wide range of input voltages.

Working Principle

The JCE0612D05 converter operates on the buck converter principle. It is a current mode control buck converter. This means that the output voltage is controlled by regulating the current flowing through the inductor. This converter is designed to switch from no-load to full load without any external components. It is also designed to have an excellent line and load regulation. This is achieved by employing a compensation circuit and a line voltage sensing network.

The converter operates by alternately connecting and disconnecting the load to and from the input voltage. When the load is connected, the inductor charges up, and when the load is disconnected, the inductor releases the stored energy and supplies the output current. The amount of energy that is stored or released in each cycle is determined by the switch and current control circuits.

The buck converter also acts as a voltage regulator since the output voltage is regulated by controlling the duration of the switch being on and off. If the input voltage rises, the duration of when the switch is on is reduced, thus resulting in a lower output voltage. If the input voltage drops, the duration when the switch is on is increased, resulting in a higher output voltage.

Conclusion

The JCE0612D05 is a small and efficient DC-DC converter suitable for use in a variety of low power applications. It operates on the buck converter principle and is designed to switch from no-load to full load without any external components. The converter also acts as a voltage regulator by controlling the duration of the switch being on or off. This converter is suited for automotive, industrial, telecom, and consumer electronics applications.
