Torex Semiconductor, Ltd. Voltage Regulators - DC DC Switching Regulators XC9236B3MD4R-G

The XC9236B3MD4R-G is a synchronous step-down DC/DC converter designed to provide a stable output voltage with high efficiency. It operates within an input voltage range of 2.0V to 6.0V and can deliver an output current of up to 600mA. The output voltage can be set externally from 0.9V to 6.0V using two external resistors, or it can be fixed within the range of 0.8V to 4.0V depending on the specific configuration. This device features automatic PWM/PFM switching control, which optimizes performance across varying load conditions, ensuring low ripple and fast response. The built-in soft start function allows for quick turn-on, with a typical soft-start time of 0.25ms for certain types. Additionally, it includes a current limiter circuit and an under-voltage lockout (UVLO) function to enhance reliability. The XC9236B3MD4R-G is suitable for applications in mobile devices, including smartphones, Bluetooth devices, and portable gaming consoles. It is available in multiple package options, including USP-6C and USP-6EL, making it versatile for different design requirements. The product is also compliant with EU RoHS standards, ensuring it meets environmental regulations.
