General Description
The G2241B provide a complete power supply
solution. They improve performance, component count,
and size compared to other multi-channel controllers
in 1-cell Li-Ion. 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. They also feature True-Shutdown
as well as internal compensation to minimize external
component count.
The G2241B also provide switched mode Li-ion
charger with dynamic power path control. G2241B
also has auto NTC-R 100kΩ/10kΩ detection circuit.
