MAX77714 Complete System PMIC, Featuring 13 Regulators, 8 GPIOs, RTC, and Flexible Power Sequencing for Multicore Applications General Description Benefits and Features The MAX77714 is a complete power-management IC Highly Integrated (PMIC) for portable devices using System-on-Chip (SoC) 4x Buck Regulators applications processors. SD0/1 Peak Efficiency > 90% at 3.6V 1.1V IN, OUT SD2/3 Peak Efficiency > 93% at 3.6V 1.8V IN, OUT Two 2A (SD2/3), one 3A (SD1), and one 4A (SD0) step- Supports LDDR4x Memory requirements down regulator switch at 2MHz, allowing the use of small 9x Low-Dropout Linear Regulator magnetic components. The output voltages for SD0 and Eight GPIOs SD1 are programmable from 0.26V to 1.52V in 10mV Real-Time Clock steps. The output voltage for SD2 is programmable from Backup Battery Charger 0.6V to 2.194V in 6.5mV steps. The output voltage for SD3 Bidirectional Reset I/O is programmable from 0.6V to 3.78V in 12.5mV steps. Interrupt Output Nine low-dropout (LDO) linear regulators supply power to System Watchdog Timer various system blocks. Each LDO features a programma- Flexible and Configurable ble active-discharge circuit in shutdown. All LDOs feature 2 I C-Compatible Interface two soft-start rates to limit inrush current during startup.
