Summary of OPTIMOS™ IPOL VOLTAGE REGULATORS WITH COT ENGINE FOR ENHANCED TRANSIENTS AND EASY DESIGN
Infineon introduces the IR3887M, IR3888M, and IR3889M OptiMOS™ IPOL voltage regulators. Designed for server, base station, telecom, and storage applications, these devices feature a fast constant-on-time (COT) engine. They offer high efficiency, high density, and precise output voltage regulation up to 30 A in compact footprints. The family supports wide input voltages, high switching frequencies up to 2 MHz, and internal overcurrent protection with selectable limits, ensuring easy design and layout while maintaining thermal stability.

Infineon Technologies AG introduces the IR3887M, IR3888M and IR3889M devices in its new family of integrated-point-of-load voltage regulators featuring a fast constant-on-time (COT) engine. This product 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 is the smallest 30 A device on the market. Fusing Infineon’s latest FET generation and enhanced package technology allows for thermal support for 30 A in a small 4 mm 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.
High switching frequency (up to 2 MHz) for small PCB size and fewer bill-of-materials (BOM) is guaranteed with easy design and layout. 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 small, 5 mm x 6 mm footprint in a PQFN package. The IR3888M handles continuous current up to 25 A and is RoHS2 compliant.
