Monolithic Power Systems, Inc. AC DC Converters, Offline Switches MP171AGS-P

The MP171AGS is a primary-side regulator designed for offline applications, capable of providing accurate constant voltage regulation without the need for an optocoupler. It supports multiple topologies including buck, boost, buck-boost, and flyback, making it versatile for various power supply designs. The integrated 700V MOSFET simplifies circuit design and reduces overall costs, optimizing it for low-power applications such as home appliances and standby power systems. This device operates efficiently at light loads due to its green-mode functionality, which reduces both peak current and switching frequency as load decreases. It has a maximum output power of 2W, with a maximum continuous output current of 60mA in continuous conduction mode (CCM) and 40mA in discontinuous conduction mode (DCM). The MP171AGS also features several protection mechanisms, including thermal shutdown, under-voltage lockout, overload protection, short-circuit protection, and open-loop detection. The product is available in a SOIC-8 package and is compliant with RoHS directives, ensuring it meets environmental standards. This makes the MP171AGS suitable for applications in consumer electronics, industrial controls, and other low-power devices.
