Renesas Electronics introduces the industry's most efficient and smallest multi-phase power management IC ISL91302B, ISL91301A/B

The ISL91302B can deliver up to 20A of output current and 94% peak efficiency for application processors, artificial intelligence processors, industrial MPUs, and FPGAs, all within the 70 mm2 solution size.

Renesas Electronics Corp. (TSE:6723), the world's leading semiconductor solutions provider, today announced the availability of three programmable power management ICs, the ISL91302B, ISL91301A, and ISL91301B, which provide the most efficient application processor for smartphones and tablets. The power management, while having the smallest board size. Several of these power management ICs also provide power management for artificial intelligence (AI) processors, FPGAs, and industrial MPUs. They are ideally suited for solid-state drives (SSDs), optical transceivers, and various consumer electronics, as well as industrial and networking equipment. Each load in the power supply. The ISL91302B single/dual output multiphase power management IC can deliver up to 20A of output current and 94% peak efficiency in a 70 mm2 solution footprint (more than 40% smaller than similar competing power management ICs).

The ISL91301A three-phase output power management IC and the ISL91301B four-phase output power management IC each provide up to 16A of output current with a peak efficiency of 94%. The new programmable power management IC introduced today uses R5 modulation technology to provide the industry's fastest single-cycle transient response, digital tuning compensation, and switching frequency up to 6MHz during load transients. These features make it easier for power supply designers to use a 2mm x 2mm, 1mm thin inductor, a small capacitor, and a small number of passive components to design a power solution.

Renesas Electronics today introduced a power management IC that does not require external compensation components or external divider resistors to set operating conditions. Each power management IC can dynamically change the number of phases of operation in the full load current range for optimum efficiency. Its ultra-low quiescent current, excellent light-load efficiency, high regulation accuracy, and fast dynamic response significantly extend the battery life of today's feature-rich, high-power electronic products.

Mark Downing, Vice President of Renesas Electronics's Core Power Solutions Division, said: "Smart phone and tablet application processors require smaller power supplies and higher output current and efficiency to maximize battery life. ISL91302B and ISL91301A / B Power Supplies Management ICs provide designers with much-needed solutions to solve the most difficult PCB layout issues, dynamically expand performance, and extend battery run time."
