Torex Semiconductor, Ltd. Voltage Regulators - DC DC Switching Regulators XC9235A3EDER-G

The XC9235A3EDER-G is a synchronous step-down DC/DC converter designed to provide a stable output voltage with a maximum output current of 600mA. It operates within an input voltage range of 2.0V to 6.0V and offers fixed output voltage options from 0.8V to 4.0V in 0.05V increments, with an adjustable output voltage option available through external resistors. The device features a built-in 0.42Oc P-channel MOS driver and a 0.52Oc N-channel MOS switching transistor, allowing for high efficiency, typically around 92%. The XC9235A3EDER-G supports oscillation frequencies of either 1.2MHz or 3.0MHz, selectable based on application needs. It includes various control methods, such as PWM for the XC9235 series, and automatic PWM/PFM switching for the XC9236 series, providing flexibility in operation. The device also incorporates a soft start feature, current limiting, and an under-voltage lockout (UVLO) function to enhance reliability. This voltage regulator is suitable for applications in mobile devices, including smartphones, Bluetooth devices, and portable gaming consoles. It is available in multiple package types, including SOT-25, USP-6C, USP-6EL, and WLP-5-03, making it adaptable for various design requirements.
