They improve performance, ponent count, and size pared 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 pensation to minimize external ponent 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.
