Torex Semiconductor, Ltd. Voltage Regulators - DC DC Switching Regulators XC9235A27D0R-G

The XC9235A27D0R-G is a synchronous step-down DC/DC converter designed to provide a fixed output voltage of 2.7V with a maximum output current of 600mA. It operates within an input voltage range of 2.0V 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 high efficiency, typically reaching up to 92%, and can be configured using only external components such as a coil and two capacitors. This regulator includes a built-in oscillator with selectable frequencies of 1.2MHz or 3.0MHz, depending on the application requirements. It operates in PWM control mode, ensuring stable performance across varying load conditions. The XC9235A27D0R-G also incorporates features such as a soft start function, current limiting, and an under-voltage lockout (UVLO) function to enhance reliability. The device is available in multiple package options, including SOT-25, USP-6C, USP-6EL, and WLP-5-03, making it suitable for various applications, including mobile devices, Bluetooth devices, and digital cameras.
