Torex Semiconductor, Ltd. Voltage Regulators - DC DC Switching Regulators XC9235A14C0R-G

The XC9235A14C0R-G is a synchronous step-down DC/DC converter designed to deliver a maximum output current of 600mA. It operates within an input voltage range of 2.0V to 6.0V and features a fixed output voltage of 1.4V. The device incorporates 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 high efficiency, typically around 92%. This regulator supports both PWM control and automatic PWM/PFM switching modes, 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 XC9235A14C0R-G is packaged in a compact SOT-25 format, making it suitable for space-constrained applications. It is compliant with EU RoHS standards, ensuring it is environmentally friendly. Typical applications include mobile devices, Bluetooth devices, and portable gaming consoles.
