MPS’S OPEN-SOURCE EMERGENCY VENTILATOR WITH EMOTIONTM AND BATTERY BACKUP
As COVID-19 spread in March of 2020, the global shortage of emergency ventilators was one of the biggest concerns. The increasing demand in ventilators meant they would soon be out of supply, so a team at Monolithic Power Systems (MPS) sought to help create a solution to this crisis. While MPS is not a medical device manufacturer, its engineers and designers are highly experienced with power elect...

We have been inspired by many other open-source projects working to battle the COVID-19 pandemic, primarily referencing the MIT E-Vent project, in our approach to ...
MPS POWER MANAGEMENT SOLUTIONS FOR POWER OVER ETHERNET (POE) SWITCHES
Modern devices are increasingly powered by Power over Ethernet (PoE), such as IP phones, wireless APs, and IP cameras. Customer premise equipment (CPE) and small base stations in the 5G era also require PoE power. Figure 1 shows common applications powered by PoE. This article discusses MPS’s comprehensive suite of power management solutions for a wide range of switches, including PSE, boo...
UNDERSTANDING POWER OVER ETHERNET AND POE CONTROLLERS AND CONVERTERS
This introduction to power over Ethernet (PoE) covers the basics of PoE standards, how PoE structure functions, and how PoE works between the PSE and PD. PoE enables an Ethernet cable to transmit DC power while also transmitting data in parallel to IP terminal devices. PoE power delivery includes two equipment types: Power-sourcing equipment (PSE) or a power provider, and powered devices (PDs) or ...
TRANSFORMING THE LOW-CARBON ERA WITH MPS'S AC/DC POWER SOLUTIONS (PART I)
The low-carbon era is leading the development trend for smaller and highly efficient chips. First, switching power supplies replaced linear power supplies in the 1980s; now, the efficiency of power supplies has significantly improved while the overall solution size has been reduced. When considering consumer requirements for portability, switching power supplies continue to become more and more ad...

The easy-to-use Design Assistant is the most popular tool provided by MPS, and its demand continues to grow each year. Figure 1 shows the annual growth of how often our Design Assistant is requested and utilized. In partic...
PRIMARY-SIDE VS. SECONDARY-SIDE REGULATION
Flyback power converters are currently some of the most common converter topologies around. This is due to the simplicity of their design and the competitive size/cost/efficiency ratio their can deliver, especially in the mid-level power range (2W to 100W). Like any converter topology, a flyback converter is composed of a power path and a control path. The power path is responsible for the conver...
Ovens are a key household appliance, and one which consumers expect to be reliable, effective, convenient, and energy efficient. The rise of smart homes has added a new layer of design requirements to new generations of ovens, including durable and intuitive user interfaces, wireless connectivity, smart sensing, and predictive maintenance. IoT capabilities can help keep up with growing consumer ex...
