G2218 Global Mixed-mode Technology 6+5+4 Channels PMU Features 2.5V ~ 5.5V Input Voltage Operation. 95% Efficient DC/DC Converter Built-in 6-ch synchronous buck converter, 5-ch LDOs, and 4-ch power switches. Low Power consumption (Sleep Mode ) < 10µA. Built-In Power ON/OFF Sequence for PMU. Built-In Short Circuit Protection (SCP), Under Voltage Protection (UVP), and cycle-by cycle current limit for DC/DC Converters. Built-In Thermal Shutdown Function.. TQFN40 Package (5mmx5mm). General Description The G2218 provide a complete power supply solution. On-chip MOSFETs provide up to 92~95% efficiency for critical power supplies. All channels DC/DC operate at one fixed frequency of 1.5MHz to optimize size, cost, and efficiency. All Synchronous converters operate at pulse skipping mode at light load.
