The MP161 integrates a 700V switching regulator, a low-dropout linear regulator, and two channel relay drivers.

Product Detail

The MP161 integrates a 700V switching regulator, a low-dropout linear regulator, and two channel relay drivers. The MP161 also has a special standby mode to minimize standby power. The MP161 is designed for home automation, industrial automation, and any other applications that adopt relays and MCUs. The 700V switching regulator adopts constant voltage (CV) regulation with internal loop compensation. Light-load efficiency is optimized by proper modulation of the switching frequency and peak current. Various protections are also included to guarantee reliable operation. The integrated low-dropout linear regulator is able to operate with an input up to 30V. The output voltage is fixed at either 5V or 3.3V. The MP161 also has over-temperature protection (OTP). Built-in relay drivers are intended to drive up to two relays using the switching regulator output. Freewheeling diodes are integrated to cut down external components. When standby mode enabled, the switching regulator output voltage is lowered to reduce power consumption. The MP161 is available in a SOIC-16 package.
