Torex Semiconductor, Ltd. Voltage Regulators - DC DC Switching Regulators XC9236B27D4R-G

The XC9236B27D4R-G is a synchronous step-down DC/DC converter designed for high efficiency and stable power supply applications. It 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. The device operates within an input voltage range of 2.0V to 6.0V and provides a fixed output voltage of 2.7V with an output current capability of up to 600mA. This regulator supports automatic PWM/PFM switching control, allowing it to adapt to varying load conditions while maintaining low ripple and high efficiency. The typical efficiency is around 92%, depending on external components. The XC9236B27D4R-G also includes features such as a soft start function, current limiting, and an under-voltage lockout (UVLO) function to enhance reliability. It is packaged in a compact 6-XDFN format, making it suitable for space-constrained applications like mobile devices, Bluetooth devices, and portable game consoles.
