Infineon Technologies AG Integrated Circuits (ICs) - PMIC - Voltage Regulators - DC DC Switching Regulators 21-0066PBF

The 21-0066PBF from Quarktwin Technology Ltd. is a DC-DC switching regulator designed for efficient voltage regulation. It operates with an input voltage range of 3.14V to 5.5V and provides adjustable output voltages from 0.8V to 3.3V. This regulator features a dual output capability with a maximum load of 15A per channel or a single output capable of handling up to 30A. The device utilizes a 2-phase synchronous buck power architecture with 180° out-of-phase operation, which helps to reduce output ripple and improve efficiency. The switching frequency is nominally set between 200kHz and 400kHz per channel, with external synchronization capability available. Protection features include overcurrent hiccup or latch, overvoltage protection, and thermal shutdown, ensuring reliable operation under various conditions. The regulator also incorporates independent soft start functionality for each output, minimizing inrush current during startup. With a compact footprint of 15.5mm x 9.25mm x 2.6mm, this product is suitable for space-constrained applications.
