B0505ST16-W5 DC/DC Converter

The new chip-level DC/DC converter, B0505ST16-W5 from Mornsun is designed to meet automotive and medical application requirements. This fixed input 0.5W DC/DC converter is the SMD device with reinforced 5KVAC high isolation and trimable output voltages of 3.3V, 3.7V, 5V, 5.4V available in a miniature SOIC16 package, with control ON/OFF pin that has a wide operating temperature of -55c to +125c.

The high-isolation, high-pressure B0505ST16-W5 DC-DC converter meets the isolation protection requirements of 2 MOPP, with an isolation voltage of 5000VAC, a system operating voltage of 849VDC, an isolation capacitor of up to 3.5pF, and is designed to meet IEC/EN 60601 standards. At a high temperature of 125 degrees C, the device can be used with a 55% load and can be widely used in industries with high-temperature requirements, such as automotive electronics.
