The XC9705 Series from Torex Semiconductor are Synchronous Step-Down DC-DC Converters that convert an input voltage of 3-36 V to an output voltage of 2.8-15 V. They include a built-in high-side driver FET and a low-side driver FET. These converters have a switching frequency between 1.2MHz and 2.2MHz. They allow external adjustment of the soft start time by connecting a resistor and capacitor to the EN/SS (Enable/Soft Start) pin, enabling the soft start time to be extended beyond the internal default setting, providing greater flexibility for various applications. These converters have a power good function that monitors the state of the output voltage. They benefit from built-in protection functions such as over-current protection and thermal shutdown. These converters are available in surface-mount packages that measure 4.5 x 2.5 x 1.5 mm and are ideal for industrial automation, industrial sensors, security systems, home appliances, 4~20ma current loop, high-voltage LDO replacement, general-purpose power-circuit and point-of-load applications.
