Torex Semiconductor, Ltd. Voltage Regulators - DC DC Switching Regulators XC9235A3HDMR-G

The XC9235A3HDMR-G is a synchronous step-down DC/DC converter designed for high efficiency and stable power supply applications. It features a built-in 600mA driver with a P-channel MOS driver transistor and an N-channel MOS switching transistor, allowing for a compact design that supports ceramic capacitors. The input voltage range is from 2.0V to 6.0V, with output voltage options available from 0.8V to 4.0V for fixed configurations, and adjustable output voltage from 0.9V to 6.0V using external resistors. This regulator operates at selectable oscillation frequencies of 1.2MHz or 3.0MHz, depending on the application requirements. The XC9235A3HDMR-G employs PWM control for efficient operation, with additional features such as a soft start function, current limiting, and an under-voltage lockout (UVLO) function to enhance reliability. It also includes a CL discharge function for rapid output voltage return during standby mode. The device is available in multiple package options, including SOT-25, USP-6C, USP-6EL, and WLP-5-03, making it versatile for various applications, including mobile devices, digital cameras, and portable gaming consoles.
