Integrated Device Technology Switching Voltage Regulators ZSPM4012BA1W33

The ZSPM4012BA1W33 is a DC/DC synchronous buck converter designed to deliver a fixed output voltage of 3.3V with a continuous output current of 2A. It operates within a wide input voltage range of 4.5V to 24V and features a fixed switching frequency of 1MHz, which allows for the use of smaller filter components, thereby reducing board space and overall material costs. This regulator incorporates several protection features, including input supply under-voltage lockout, output voltage soft start, current limit, over-voltage protection, and thermal shutdown. It also has a low quiescent current of less than 10µA when disabled, contributing to increased efficiency and battery life in portable applications. The device is packaged in a compact 16-pin QFN (3x3mm) format, making it suitable for space-constrained designs. Typical applications for the ZSPM4012BA1W33 include wireless access points, set-top boxes, and portable devices such as smartphones and tablets. The product is supported by an evaluation kit and comprehensive documentation for ease of integration into various projects.
