Torex Semiconductor, Ltd. Voltage Regulators - DC DC Switching Regulators XC9142F43DER-G

The XC9142F43DER-G is a synchronous step-up DC/DC converter capable of delivering up to 0.8A output current. It operates with an input voltage range of 0.65V to 6.0V and can generate a fixed output voltage between 1.8V and 5.5V in 0.1V increments. The device features a built-in oscillator with selectable frequencies of 1.2MHz or 3.0MHz, allowing for flexibility in application design. This regulator includes several protective features such as over-current limit and output short-circuit protection. It also offers various operational modes, including PWM and PWM/PFM control, which can enhance efficiency based on load conditions. The XC9142F43DER-G is suitable for portable and battery-operated devices, making it ideal for applications in mobile equipment, wearable devices, and PC peripherals. The product is packaged in a compact SOT-25 format and is compliant with EU RoHS standards.
