Description
The MIE1W0505BGY is an isolated, regulated, DC/DC power module. It can support 3V to 5.5V input voltage (VIN) applications. The MIE1W0505BGY features excellent load and line regulation, supporting up to 1W of output power (POUT).
The MIE1W0505BGY integrates the power MOSFET, transformer, and feedback circuit all in one chip, achieving excellent performance and saving size. When the output voltage (VOUT) is below the target VOUT, the IC starts switching to deliver power from VIN to VOUT. Once VOUT rises to the target VOUT, switching stops.
The MIE1W0505BGY uses capacitive isolation technology for feedback blocking, which can regulate VOUT without the need for a traditional optocoupler. This module provides a smaller size and higher reliability operation compared to traditional isolated power modules. The MIE1W0505BGY features continuous short-circuit protection (SCP) and over-temperature protection (OTP).
It is available in a compact SOIC-16 wide-body (WB) package.

HOW TO APPLY AN ISOLATED POWER MODULE IN SIGNAL ISOLATIONARTICLESignal transmissions are everywhere. In industrial applications, such as electric vehicle (EV) charging stations and automation systems with programmable logic controllers (PLCs), there is a high voltage (up to several kV) that can be dangerous to the human body. This type of hazardous voltage can also pass through the signal line, which can cause signal interference and could eventually destroy t...
