Infineon has introduced a family of integrated-point-of-load voltage regulators featuring a fast constant-on-time (COT) engine.

Devices in the family are designated IR3887M, IR3888M and IR3889M.

The  family is designed for today’s server, base station and telecom (operating at 85˚C ambient temperature) and storage applications requiring both high efficiency and high density.

The IR3887M 30A device fuses Infineon’s latest FET generation and package technology and delivers thermal support for 30A in a 4mm x 5 mm footprint.

The OptiMOS IPOL product family comes with an enhanced-stability COT engine with ceramic capacitors without the need for external compensation. Wide input voltage range of 4.3 V – 17 V, 2 V min with 5 V external bias, and precise output voltage (0.5 % accurate reference voltage) are supported.

The voltage regulators offer high efficiency at light-load and thermally-compensated internal overcurrent protection with four selectable limits for a less expensive and smaller inductor. Switching frequency is up to 2MHz.

These products provide benchmark efficiency, low power losses and the ability to thermally handle up to 30 A of continuous current. Customers can also benefit from the benchmark output voltage regulation and enhanced load transients response.

The IR3888M and IR3889M come in a 5 mm x 6 mm footprint in a PQFN package.

The IR3888M handles continuous current up to 25 A and is RoHS2 compliant.

The IR388M and IR3889M are in stock now. The IR3887M device is also planned for release in 2020
