Monolithic Power Systems MP110 flyback regulator and EV110-P-00A evaluation board

Monolithic Power Systems (MPS) has announced the MP110, a monolithic 900 V flyback regulator that is designed specifically for electronic meters, supporting wireless communication. The product offers robustness, ease-of-use, and smart-home and building compatibility.

The device features the robust performance of MPS 900 V process technology. In addition to a low ohmic switching FET that supports over 8 W of output power, the technology also features a rugged 900 V start-up depletion FET for low no load power dissipation. The 900 V monolithic integrated solution enables overtemperature protection that is on the same silicon of the 900 V power FET, offering precise thermal protection. It also offers a full suite of protection features.

The product is designed to minimise electromagnetic interference for wireless communication in home and building automation applications. The operating frequency is externally programmed with a single resistor so that the power supply’s radiated energy can be designed to avoid the wireless frequency transmission. The integration of the 900 V switching FET and its switching characteristic simplifies the power stage design. The optimised internal blanking, along with built-in soft start, simplifies the design and lowers component count.

Its features are suitable for any ACDC application that requires high reliability, including large appliances, medical, industrial controls, and any product that is sold where the power grid is not stable.

The EV110-P-00A evaluation board is designed to demonstrate the capabilities of the MP110 and is also designed for offline high input voltage (85-420 VAC) application with triple outputs (13.5 V/300 mA, 8 V/50 mA,8 V/50 mA). The 8 V output rail can power the LDO for MCU power supply.

The board meets EN55022 conducted EMI requirements with its frequency jittering function. It has overtemperature protection, VCC under voltage lockout, overload protection, overvoltage protection, short-circuit protection and built-in PRO pin for extra protection setting.
