Torex Semiconductor, Ltd. Voltage Regulators - DC DC Switching Regulators XC9237G39D4R-G

The XC9237G39D4R-G is a synchronous step-down DC/DC converter from Quarktwin Technology Ltd., designed to provide a fixed output voltage of 3.9V with a maximum output current of 600mA. It operates within an input voltage range of 1.8V to 6.0V and features a built-in P-channel MOS driver transistor with a resistance of 0.42Oc and an N-channel MOS switching transistor with a resistance of 0.52Oc. The device supports both PWM control and automatic PWM/PFM switching modes, allowing for efficient operation across varying load conditions. This regulator is optimized for low power consumption, with a standby current of 1.0OºA or less, and includes a high-speed soft-start function, particularly beneficial for applications requiring quick turn-on times. The XC9237G39D4R-G is suitable for use in mobile devices, Bluetooth applications, 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.
