Torex Semiconductor, Ltd. DC DC Switching Controllers XC9301A582MR-G

The XC9301A582MR-G is a step-up/down DC/DC converter controller IC designed for applications requiring efficient power management. It operates within an input voltage range of 2.0V to 10V and provides a selectable output voltage range from 2.4V to 6.0V in 0.1V increments, with an accuracy of ¬±2.5%. The device features built-in fast, low ON resistance drivers and can deliver an output current of up to 250mA at 3.3V output. The switching frequency can be set at either 180kHz or 300kHz, allowing for flexibility in design. The XC9301A582MR-G incorporates a soft-start function to mitigate inrush currents and voltage overshoot during power-up. In shutdown mode, the device consumes a minimal standby current of 0.5OºA or less. It is packaged in a compact SOT-25 format and is compliant with EU RoHS standards, making it suitable for environmentally conscious designs. This product is ideal for use in mobile phones, PDAs, portable audio equipment, and various power supply applications.
