Multiphase PMICs deliver up to 20A and 94% peak efficiency
The ISL91302B dual/single output, multiphase PMIC provides up to 20A of output current and 94 percent peak efficiency in a 70mm2 package. That is more than 40 percent smaller than competitive PMICs, claims Renesas.
The ISL91301A triple output PMIC and ISL91301B quad output PMIC both deliver up to 16A of output power with 94 percent peak efficiency. The programmable PMICs leverage Renesas’ R5 Modulation Technology to provide fast single-cycle transient response, digitally tuned compensation, and ultra-high 6 megahertz (MHz) (max) switching frequency during load transients. These features make it easier for power supply designers to design boards with 2x2mm, 1mm low profile inductors, small capacitors, and only a few passive components. The devices do not require external compensation components or external dividers to set operating conditions. Each PMIC dynamically changes the number of active phases for optimum efficiency at all output currents. Their low quiescent current, superior light load efficiency, regulation accuracy, and fast dynamic response significantly extend battery life for today’s feature-rich, power hungry devices.
