Torex Semiconductor, Ltd. Voltage Regulators - DC DC Switching Regulators XC9236A28D0R-G

The XC9236A28D0R-G is a synchronous step-down DC/DC converter designed to provide a fixed output voltage of 2.8V with a maximum output current of 600mA. It operates within an input voltage range of 2.0V to 6.0V and 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. The device supports high efficiency, typically reaching 92%, and can be configured using only external components such as a coil and two capacitors. This regulator utilizes automatic PWM/PFM switching control, allowing it to adapt to varying load conditions while maintaining low ripple and fast response times. It includes features such as a soft start function, current limiting, and an under-voltage lockout (UVLO) function that disables the output when the input voltage drops below 1.4V. The XC9236A28D0R-G is suitable for applications in mobile devices, smartphones, and portable gaming consoles, among others. It is available in multiple package options, including USP-6C and USP-6EL, and is compliant with EU RoHS standards.
