Torex Semiconductor, Ltd. Voltage Regulators - DC DC Switching Regulators XC9235C3BDER-G

The XC9235C3BDER-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 externally adjustable option allowing output voltages from 0.9V to 6.0V. The device 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, enabling high efficiency of up to 92%. The XC9235C3BDER-G supports oscillation frequencies of either 1.2MHz or 3.0MHz, depending on the configuration, and includes various control methods such as PWM and automatic PWM/PFM switching. It incorporates features like a soft start function, current limiting, and an under-voltage lockout (UVLO) function to enhance performance and reliability. The device is packaged in a compact SOT-25 format and is compliant with EU RoHS standards, making it suitable for applications in mobile devices, digital cameras, and other portable electronics.
