(1) Primary Step-down DC/DC Converter
- Sufficient input voltage range and output current for various industrial equipment, and easy-to-use frequency (XC9270/71).
- With the VIN terminal absolute maximum rating of 36V and a maximum surge voltage of 46V (during 400ms), the XC9270/71 can operate in demanding industrial applications that require protection against transient surge voltages
(2) Secondary Step-down DC/DC Converter for powering the MCU / FPGA / Sensor
- Stable operation, small size and low EMI are realized by placing Micro DC/DC Converts with integrated Inductors (XCL201/02, XCL205/06, XCL211/12) close to the Point of Load on the PCB.
(3) Voltage detector for monitoring the 12V/24V input
- 12V/24V input monitoring using a Voltage detector with separated sense pin.
- RESETB signal monitoring at 12V/24V input voltage drop is output to the MCU / FPGA, and after the shutdown process, the DC/DC can be stopped according to the sequence using the RC delay. It can be easily configured using the CMOS output type of the voltage detector (XC6118).
- Any detect / release voltage can be set by using the external adjustable hysteresis function. In addition, it supports not only release delay but also detection delay. (XC6134).
(4) Step-up DC/DC for various input or output devices such as OLED / LED
- Small size Step-up DC/DC for OLED / LED etc. (XC9119)
