Torex Semiconductor, Ltd. Voltage Regulators - DC DC Switching Regulators XC9236B34DMR-G

The XC9236B34DMR-G is a synchronous step-down DC/DC converter designed for high efficiency and stable power supply applications. It operates within an input voltage range of 2.0V to 6.0V and provides a fixed output voltage of 3.4V with a maximum output current of 600mA. 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, allowing for the use of ceramic capacitors. This regulator supports automatic PWM/PFM switching control, which optimizes performance across varying load conditions, ensuring low ripple and fast response. The XC9236B34DMR-G includes a soft start function, a current limiter circuit, and an under-voltage lockout (UVLO) feature that disables the output when the input voltage drops below 1.4V. It also incorporates a CL discharge function for rapid output voltage return during standby mode. The device is available in a compact SOT-25 package and is compliant with EU RoHS standards, making it suitable for environmentally friendly applications. Typical applications include mobile devices, Bluetooth devices, and portable gaming consoles.
