Infineon Technologies has launched the IRPS5401, a five-output point of load (POL) digital voltage regulator for FPGAs, ASICs, and other multi-rail power systems. The IRPS5401has been developed as a fully integrated PMIC solution that replaces multiple regulators with a single device in a 7mm x 7mm 56 pin QFN package. Infineon said it supports current and future applications in high density ASIC and FPGA. Additional applications comprise CPU multi-rail systems, embedded computing systems, and communication and storage systems. The IRPS5401 forms a key part of the UltraZed system on a module (SOM) from Avnet. The compact package size combined with PMBus communication for real-time monitoring and control provides the optimized power management solution that the UltraZed requires. The IRPS5401 is designed for single rail operation ranging from 5V to 12V, where most PMICs are only 5V. It has one 500mA LDO output, and four configurable switching regulator outputs, two at 2A, and two at 4A. The outputs of the IRPS5401 can be used to provide the typical rails required for core, memory, and I/O voltages. The voltage output range is between 0.5V and 3.6V for regulators A to D, and between 0.25V and 5.1V for the LDO. Switching regulator A can output up to 50A if combined with an external power stage. Switching regulators C and D can be combined to deliver 8A in a low ripple, dual-phase configuration. All outputs are well within the power requirements of most FPGAs and ASICs ranging between 10W to 50W,

Infineon Technologies is expanding its recently launched CoolMOS P7 technology with a SOT-223 package. The device has been developed as a one-to-one drop-in replacement for DPAK. It is fully compatible with a typical DPAK footprint, according to the vendor. The combination of the new CoolMOS P7 platform with the SOT-223 package is meant for applications such as charger for smartphones, laptop adapters, TV power supply, and lighting. The new CoolMOS P7 is designed to address needs of the low power SMPS market. It uses Superjunction technology, which results in a reduced overall bill of materials (BOM) on the customer side, according to Infieneon. The SOT-223 package is a DPAK alternative and well established in price sensitive markets. The thermal behavior of the CoolMOS P7 in this package was assessed across several applications. When the SOT-223 was placed on a DPAK footprint, the temperature increased by a maximum of 2-3 degrees C compared to a standard DPAK. The CoolMOS P7 in SOT-223 is available in 600 V, 700 V, and 800 V devices.

Infineon Technologies' OptiMOS Linear FET product family combines R DS(on) (on-state resistance) of a trench MOSFET with the wide safe operating area of a planar MOSFET. This solves the trade-off between R DS(on) and linear mode capability, according to the vendor. The OptiMOS Linear FET can operate in the saturation region of an enhanced mode MOSFET for hot-swap, e-fuse, and protection applications commonly found in telecom and battery management systems (BMS). Both the rugged linear mode operation and the higher pulse current contribute to low conduction losses, faster start-up, and shorter down time, according to Infineon. The OptiMOS Linear FET prevents damage at the load if there is a short circuit, by limiting high in-rush currents. The OptiMOS Linear FET is available in three voltage classes: 100 V, 150 V, and 200 V. They can be supplied in either a D2PAK or D2PAK 7pin package. These industry standard packages offer a compatible footprint for drop-in replacement.
