Integrated Device Technology Voltage Regulators - DC DC Switching Regulators ZSPM4011BA1W15

The ZSPM4011BA1W15 is a synchronous buck converter designed for high efficiency with a fixed output voltage of 1.5V. It supports a wide input voltage range from 4.5V to 24V and can deliver up to 1A of continuous output current. The device operates at 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 features current mode pulse-width modulation (PWM) control and includes several built-in protection mechanisms such as input supply under-voltage lockout, output voltage soft start, current limit, over-voltage protection, and thermal shutdown. In disabled mode, it consumes less than 10µA of quiescent current, making it suitable for battery-powered applications. The ZSPM4011BA1W15 is packaged in a compact 16-pin QFN (3x3mm) format, facilitating easy integration into various electronic designs. Typical applications include wireless access points, set-top boxes, and portable devices.
