High performance PMIC delivers complete power solution

The RAA215300 includes six buck regulators, three LDOs and a coin cell/supercap charger. It supports DDR4, DDR4L, DDR3 and DDR3L memory with dedicated VREF, VTT and VPP rails. The new PMIC enables four-layer printed-circuit boards, which reduce costs. The high level of integration also increases system reliability due to fewer system components needed on the board.

The RAA215300 pairs with the RZ/G2L, RZ/V2L and several other Renesas offerings in a Winning Combination for a Scalable SMARC (Smart Mobility ARChitecture) SoM System-on-Module with AI design.

In addition to the Renesas MPU and PMIC, this Winning Combination includes power controllers, a USB PD controller, and a clock device from Renesas. Renesas offers over 250 of these Winning Combinations that consist of complementary analogue, power, timing devices and embedded processing, and provide an easy to use architecture. They simplify the design process and significantly reduce design risk for customers in a wide variety of applications.

“Customers of our RZ/V2L and RZ/G2L MPUs will enjoy the performance advantages and ease-of-design of the RAA215300,” said Andrew Cowell, Vice President, Mobility, Infrastructure and IoT Power Business Division at Renesas.

“In addition, its high integration and rich feature set makes it an excellent choice for consumer, industrial and SoM applications.”
