Torex Semiconductor, Ltd. Voltage Regulators - DC DC Switching Regulators XC9236C13D4R-G

The XC9236C13D4R-G is a synchronous step-down DC/DC converter designed for high efficiency and stable power supply applications. It features a built-in 0.42Oc P-channel MOS driver transistor and a 0.52Oc N-channel MOS switching transistor, allowing for the use of ceramic capacitors. The input voltage range is from 2.0V to 6.0V, with a fixed output voltage of 1.3V and a maximum output current of 600mA. The device operates with an oscillation frequency of 1.2MHz or 3.0MHz, selectable to suit specific applications. It incorporates automatic PWM/PFM switching control for improved efficiency across varying load conditions and includes features such as a soft start function, current limiting, and an under-voltage lockout (UVLO) function. The XC9236C13D4R-G is available in a compact 6-XDFN package, making it suitable for space-constrained applications like smartphones, mobile devices, and portable electronics.
