描述
The RRG5341x-A10 is a highly integrated, highly efficient PMIC with programmable, precise output voltage power solution for LPDDR5/5X CAMM2 modules, with four step-down switching output regulators and two LDO output regulators. This PMIC is fully compliant with the JEDEC PMIC5200 specification. It is powered from two input power supplies (VIN and VIN_Bulk) from the system board for its switching and LDO output regulators.
The RRG5341x-A10 has numerous advanced protection schemes to protect itself and the entire BOM of the CAMM2 modules. This PMIC offers secure mode operation to defend against malicious attacks and has an advanced I3C bus that can operate at a maximum speed of 12.5MHz with low-voltage I/O operation.
The RRG5341x-A10 is available in a small 5mm × 5mm form factor in 35-VFQFPN package with enhanced solder joint reliability and thermal dissipation.
