Torex Semiconductor, Ltd. DC DC Switching Controllers XC9302A432MR-G

The XC9302A432MR-G is a step-up/down DC/DC converter controller IC designed for efficient power management in various applications, including mobile phones and portable audio equipment. It operates within an input voltage range of 2.0V to 10V and provides a selectable output voltage range of 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. This controller supports both PWM and PFM control modes, optimizing efficiency across different load conditions. The switching frequency can be set to either 180kHz or 300kHz, allowing flexibility in design. The XC9302A432MR-G includes a soft-start feature to mitigate inrush currents and voltage overshoot during power-up, and it has a low standby current of 0.5OºA or less when disabled. The device is packaged in a compact SOT-25 format and is compliant with EU RoHS standards, making it suitable for environmentally conscious designs.
