ILDC12-15E: Isolated 1/4W 3.3-to-5V DC-DC Conv, 1kV, DFN6

The ILDC12-15E is a one-quarter watt fully-regulated 3.3V-to-5V DC-DC boost convertor in an ultraminiature 3 mm x 5.5 mm DFN6 package. The part can be used to generate isolated RS-485 bus supplies, or power high-side gate supplies in H-bridges.

NVE’s proven IsoLoop® isolation technology and a unique ceramic/polymer composite barrier provide 1 kV isolation and virtually unlimited barrier life.

The device minimizes board space and parts count, requiring just three external capacitors. No additional regulation is required and there is no minimum load.

Frequency hopping and shielding reduce EMI, and ferrite beads are not necessary for EMI mitigation.

A high-temperature process allows up to 175 °C junction temperature for full power up to 125 °C operating temperature with no derating. Integrated short-circuit protection avoids excessive power dissipation.
