Renesas Electronics ISL91302B, ISL91301A and ISL91301B multiphase PMICs

Renesas Electronics has announced three programmable power management ICs (PMICs) that offer high power efficiency and a small footprint for application processors in smartphones and tablets: the ISL91302B, ISL91301A and ISL91301B PMICs.

The PMICs also deliver power to artificial intelligence (AI) processors, FPGAs and industrial microprocessors (MPUs) and are suitable for powering the supply rails in solid-state drives (SSDs), optical transceivers and a wide range of consumer, industrial and networking devices. The ISL91302B dual/single output, multiphase PMIC provides up to 20 A of output current and 94% peak efficiency in a 70 mm² solution size that is more than 40% smaller than competitive PMICs, according to the company.

In addition to the ISL91302B, Renesas’s ISL91301A triple-output PMIC and ISL91301B quad-output PMIC both deliver up to 16 A of output power with 94% peak efficiency. The programmable PMICs leverage Renesas’s R5 Modulation Technology to provide fast single-cycle transient response, digitally tuned compensation and ultrahigh 6 MHz (max) switching frequency during load transients. These features make it easy for power supply designers to design boards with low-profile inductors, small capacitors and only a few passive components.

The PMICs 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, good light load efficiency, regulation accuracy and fast dynamic response extend battery life for feature-rich, power-hungry devices.
