JCA0624D01 Datasheet/PDFDC DC Converters
The JCA0624D01 is a DC DC converter designed to help achieve power supply conversion with high efficiency, ripple, and linearity. It is capable of efficiently converting a signal from one electrical potential to another, providing reliable power conditioning for many different applications.
Applications
The JCA0624D01 is designed to provide quality electrical regulation for several applications. It is a great choice for several power electronics applications, including industrial, automotive, telecom, computer, and instrumentation. Its versatility also ensures a wide range of applications, such as battery charger, voltage regulator, and frequency synthesizer.
Working principle
The JCA0624D01 is designed based on a buck-boost switching regulator topology, which utilizes an NMOS transistor-based switch controller to support both buck and boost mode operations. When the control output is turned off, the NMOS transistor releases current to charge the inductor and flyback diode in buck mode. When the control output is turned on, the stored energy in the inductor gets discharged into the output capacitor in boost mode. The converter then transfers the DC input voltage into a defined DC voltage output level, with the switching frequency adjusting accordingly.
In order to provide better efficiency and output accuracy, the JCA0624D01 integrates a 500kHz oscillator and a 5-bit voltage reference amplifier. The oscillator serves as the master clock of the control module and controls the on/off timing of the NMOS transistor. The voltage reference amplifier maintains a good analog performance while avoiding large discrepancies due to process temperature variation.
Advantages
The benefits of using the JCA0624D01 compared to other converters are diverse. For starters, it is designed to operate over wide input voltage ranges of 3.3 to 32V. This allows for the support of most common power sources and adapts to conditioins such as those caused by car batteries that can rapidly decline in voltage. It also features a wide output voltage set range of 0-100%. This feature helps the JCA0624D01 provide various voltage outputs per system voltage range.
Additionally, the JCA0624D01 has an extremely low quiescent current, which is as low as 1.5mA. This lowers heat dissipation, increases efficiency, and saves power while making sure the quality of the electrical regulation remains consistent. Another bonus feature of the JCA0624D01 is its voltage error rate, or how well the output voltage accurately follows the design level. The JCA0624D01 is designed to have a voltage error rate better than 0.5%. This is beneficial for applications that require precise power conversion.
Conclusion
The JCA0624D01 is an excellent choice for those looking for a reliable DC DC converter. Its ability to operate over wide input voltage ranges, its wide output voltage set range, its low quiescent current, and its high voltage error rate make it suitable for a wide variety of applications.
