5V, 1W, Regulated, 2.5kVRMS Isolated DC/DC Module
MIE1W0505BGLVH
The MIE1W0505BGLVH is an isolated, regulated DC/DC module. It can support 3V to 5.5V input voltage (VIN) applications. With excellent load and line regulation, it supports up to 1W of output power (POUT).
The MIE1W0505BGLVH integrates power MOSFETs, a transformer, and a feedback (FB) circuit all in one chip, achieving excellent performance and saving size.
The MIE1W0505BGLVH supports a regulated output voltage (VOUT). When VOUT drops below the target voltage (3.3V or 5V), the IC begins switching, delivering power from the VIN pin to the VOUT pin until VOUT reaches the target voltage again.
The MIE1W0505BGLVH also integrates a VOUT feedback block, which can regulate VOUT without the need for a traditional optocoupler and a precision configurable reference IC. This small solution provides high reliability compared to traditional isolated power modules.
Full protection features include short-circuit protection (SCP) and over-temperature protection (OTP).
The MIE1W0505BGLVH is available in a small LGA-12 (4mmx5mm) package
