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.
