Torex Semiconductor, Ltd. Voltage Regulators - DC DC Switching Regulators XC9237G15C4R-G

The XC9237G15C4R-G is a synchronous step-down DC/DC converter designed for high efficiency and stable power supply applications. It features a built-in 0.42Oc P-channel MOS driver transistor and a 0.52Oc N-channel MOS switching transistor, allowing for the use of ceramic capacitors. The operating voltage range is from 1.8V to 6.0V, with an output voltage that can be set externally from 0.9V to 6.0V. The device supports an output current of up to 600mA and offers selectable oscillation frequencies of 1.2MHz or 3.0MHz. This regulator operates in PWM mode and can also switch to automatic PWM/PFM mode, providing flexibility for various load conditions. It includes features such as a soft start function, current limiting, and an under-voltage lockout (UVLO) function to enhance reliability. The XC9237G15C4R-G is suitable for applications in mobile devices, Bluetooth devices, and portable gaming consoles, among others. It is available in multiple package options, including SOT-25 and USP-6C, and is compliant with EU RoHS standards.
