Torex Semiconductor, Ltd. Voltage Regulators - DC DC Switching Regulators XC9236A2KD4R-G

The XC9236A2KD4R-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 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 available from 0.8V to 4.0V in 0.05V increments, and an adjustable output voltage option starting from 0.9V using external resistors. This regulator can deliver an output current of up to 600mA and operates at selectable oscillation frequencies of either 1.2MHz or 3.0MHz, depending on the application requirements. The XC9236 series utilizes automatic PWM/PFM switching control, which enhances efficiency across varying load conditions. Additional features include a low standby current consumption of 1.0OºA or less, built-in soft start, and under-voltage lockout (UVLO) functionality. The device is available in multiple package options, including SOT-25, USP-6C, USP-6EL, and WLP-5-03, making it suitable for a variety of applications such as smartphones, mobile devices, and digital cameras. The XC9236A2KD4R-G is also compliant with EU RoHS standards, ensuring it meets environmental regulations.
