The new XC9270/71 series is a step-down (buck) DC/DC converter with integrated 0.3Ω N-ch driver Transistor that utilises a bootstrap configuration. The operating input voltage range is 7.0V to 30V and the XC9270/71 can also withstand surge voltages of 46V for up to 400ms. This resilience, coupled with an operating temperature range of -40 OC to +105OC makes the XC9270/71 an ideal choice for more demanding Industrial applications.

 

                        


Using the internal 0.8V reference voltage, the output voltage can be set using two external resistors within a range of 1.2V to 12V. To ensure maximum efficiency at higher output loads the designer can select fixed frequency PWM mode using the MODE/SYNC pin or alternatively PFM/PWM automatic switching can be used for improved efficiency during light loads.
The XC9270/71 is readily available in a SOP-8FD package measuring 6.0mm x 4.9mm x 1.55mm and the package incorporates an exposed GND tab to maximise heat dissipation.

The new XC6130/31 voltage detector has a built-in adjustable watchdog timer for high reliability applications where the system needs to be able to recover from code errors without human intervention. The XC6130/31 comes with an N-channel open drain output and is configured as Detect Low (RESETB). The Detect Voltage Range can be set between 1.6V and 5.0V in 0.1V steps.

                         


With a revised internal circuit which offers improved Temperature Characteristics (±50ppm/degC), higher detector threshold accuracy (±1.0% at 25˚C) and low power consumption (9.8µA), the XC6130/31 is ideally suited for monitoring a wide range of microprocessors, in all types of battery powered applications.

The XC6130/31 is available in the SOT-26 package
