The EL7512CYZ is a DC-DC switching controller designed for use in negative power supply applications. It can be used for applications that require a negative voltage rail for devices such as voltage leveltranslation, logic level conversion and power sequencing. This device supports a wide input voltage range from -20V to -60V and provides switching frequency up to 1 MHz. It includes a wide range of safety features such as slew rate control, input/output over-current protection and thermal shutdown.

Overview of EL7512CYZ Application Field

EL7512CYZ is well suited for medical and industrial applications that require a negative voltage rail or voltage level conversion. It can be used to generate a negative supply rail for use in medical imaging and other medical equipment. It is also suitable for industrial applications such as analog-to-digital converters, motor drives and other applications where a negative voltage rail is critical. In addition, the device can be used for applications that require a high switching frequency, such as power sequencing, logic level conversion and PoE (Power over Ethernet).

EL7512CYZ Working Principle

The EL7512CYZ requires a minimum of two external components in order to operate. These two components are an inductor and a Schottky diode. The inductor and diode must be selected for the desired application parameters such as output voltage, load current, and output ripple. The device uses the inductor and diode to convert the input voltage to the desired output voltage. The device has a number of features that allow the user to adjust the performance of the regulator such as soft start, output current limit and output voltage under-voltage lockout.

The controller includes an over-current protection, which prevents damage to the device and the system when the load current exceeds the limit. As the load current increases, the device reduces the switching frequency and reduces the output voltage in order to limit the inductor current. The controller also has a thermal shutdown protection which will shut down the system if the device temperature reaches a certain limit.

Conclusion

The EL7512CYZ is a versatile and reliable DC-DC switching controller which can be used in a wide range of applications. It is suitable for medical and industrial applications and can be used to generate a negative voltage rail. The device has a number of built-in features such as over-current protection, thermal shutdown and soft start. It is a cost-effective solution for applications that require a negative voltage rail and/or a high switching frequency.
