PMIC RAA215300 with Built-In-Charger Enables Four-Layer Printed Circuit Boards and Reduces Design Complexity

Renesas Electronics Corporation has introduced new Power management IC “RAA215300” that offers nine channels, a built-in charger, and a real-time clock. The new high-performance PMIC reduces design complexity and enables four-layer printed-circuit boards. This Device is optimized to complement RZ/V2L and RZ/G2L microprocessors, designed for AI-enabled applications. PMIC RAA215300 supports multiple DDR memories, multiple processors, SoCs, and single-cell Li-Ion battery applications. Moreover, it includes six buck regulators, three LDOs, and a coin cell/supercap charger.

The RAA215300 PMIC supports -40°C to 105°C ambient temperature for industrial applications and improves system power efficiency with VTT buck regulator. It supports DDR4, DDR4L, DDR3 and DDR3L memory with dedicated VREF, VTT and VPP rails. This Device is fully configurable with built-in EEPROM and has built-in watch dog timer for secure system power up. Moreover, it has an ultrasonic mode to eliminate audible noise coupling into microphones.
