DESCRIPTION
The MID1W0505A 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. It is available in a low-profile, wide body SOICW-16 package.
