Torex Semiconductor, Ltd. Voltage Regulators - DC DC Switching Regulators XC9236A39D4R-G

The XC9236A39D4R-G is a synchronous step-down DC/DC converter designed for high efficiency and stable power supply applications. It operates within an input voltage range of 2.0V to 6.0V and provides a fixed output voltage of 3.9V with a maximum output current of 600mA. The device features a built-in P-channel MOS driver transistor with a resistance of 0.42Ω and an N-channel MOS switching transistor with a resistance of 0.52Ω, allowing for the use of ceramic capacitors. The XC9236A39D4R-G utilizes automatic PWM/PFM switching control, which optimizes performance across varying load conditions, ensuring low ripple and fast response. It includes a soft start function, reducing inrush current during startup, and has a low standby current consumption of 1.0OºA or less. The device is available in a compact 6-XDFN package, making it suitable for space-constrained applications such as mobile devices, Bluetooth devices, and portable game consoles. This product is compliant with EU RoHS standards and is environmentally friendly, making it a viable option for engineers looking for reliable voltage regulation solutions in their designs.
