MP2315GJ-Z step-down DC-DC converter Chip 0.8V 1 Output 3A
The MP2315GJ-Z, manufactured by Monolithic Power Systems (MPS), is a high-efficiency synchronous step-down DC-DC converter packaged in a space-saving 8-pin TSOT23-8, designed for compact power management applications. It features a wide input voltage range of 4.5V to 24V, supports a continuous output current of 3A, and an adjustable output voltage from 0.8V to 22.8V, with a fixed switching frequency of 500kHz that can be synchronized to an external clock ranging from 200kHz to 2MHz. Equipped with built-in internal power MOSFETs (low Rds(on)), it achieves up to 95% conversion efficiency, low quiescent current, and current-mode operation for fast transient response and stable loop performance, along with protection features including over-current protection (OCP), thermal shutdown, and internal soft start.
This chip is widely applicable to various electronic devices, mainly including: notebook systems and I/O power supply, flat panel televisions and monitors, digital set-top boxes, wearable devices (such as smart bracelets and smart rings), smart home equipment, mini drones, and Arduino DIY projects, as its compact size and high efficiency can save up to 60% PCB space and avoid interference to other components.
