Torex XC9702

XC9702 – 60 V 0.3 A Step-Down DC/DC with Integrated Inductor

The XC9702 series is the world’s smallest 60 V 300 mA DC/DC Solution.

XC9702 Synchronous Step-Down DC/DC Converters feature built-in Nch-Nch driver FETs on an extremely small 9.4 x 7.4 mm mounting area. The converters operate with a 60 V high-voltage rating and a 300mA output current while accommodating small peripheral components. The XC9702 series offers a MODE terminal, allowing PWM control or PWM/PFM automatic switching control operation settings. The flexible operation enables noise reduction and lowers power consumption in various applications.

The XC9702 Synchronous Step-Down DC/DC Converters provide different protection functions, including current limiting, output overvoltage, Lx short-circuit protection, and thermal shutdown. These protections ensure safe operation in abnormal conditions. The converters are ideal for various applications, including 24 V battery systems, industrial automation/sensors, security systems, home appliances, high-voltage LDO replacement, and general-purpose power circuits.

Available in a USP-10B, DFN3030-12A and HSOP-8N packages.
