MONOLITHIC POWER SYSTEMS (MPS) MID1W0505AGY-3S-P DC-DC Switching Regulator, Isolated, Fixed, Semi Regulated, 3 kV, 4.5 to 5.5 V In, 5 V Out, WSOIC-16

MID1W0505AGY-3S-P is a semi-regulated, isolated DC/DC converter that can support 4.5V to 5.5V input voltage (VIN) applications across a -40°C to +125°C operating temperature range. It has excellent load regulation, line regulation, and supports up to 1W of output power (POUT). The device integrates a power MOSFET, transformer, and feedback (FB) circuit all in one chip. The MID1W0505A is a small solution that provides high reliability compared to traditional isolated power modules. Full protection features include short-circuit protection (SCP), over-current protection (OCP), and OTP protection. The MID1W0505A requires a minimal number of readily available, standard external components. Applications include industrial automation systems, isolated bias power for digital isolators, isolated bias power for RS-485, RS-422, and CAN Interfaces, isolated sensor power supplies, telecom and network devices (e.g. 5G RRUs, industrial CPE, and network gateways).
