The IC features built-in frequency jittering technology. By slightly varying the switching frequency automatically, it spreads electromagnetic interference (EMI) across a broader spectrum, significantly reducing the size and cost of the required input EMI filter components. 2. Comprehensive Protection Suite
Utilizes cycle-by-cycle monitoring via the current-sense amplifier to instantly limit output energy during short circuits.

Senses the current passing through the internal power switches cycle-by-cycle. It limits the duty cycle if an overload or short-circuit condition occurs.
No. The absolute maximum VDD is 10V, but the detection thresholds are fixed for a single Li-ion cell (3.6V-4.2V). For 2S packs, look for a dedicated 2S protection IC.
The IC is a QFN‑16 with an exposed thermal pad. Soldering requires a hot‑air station and proper flux; overheating may damage the chip or surrounding components.
