MP2762A 4-21V I2C-Controlled 6A Buck or Boost Charger QFN-30
The MPS MP2762A is a I2C-Controlled 6A Buck or Boost Charger. It operates from a 4 V to 21 V input and is rated for 6 A. It is supplied in a QFN-30 package.
The MP2762A is a highly integrated buck or boost charger IC with narrow voltage DC (NVDC) power path management and USB On- the-Go (OTG) for battery packs with two cells in series.

Design Notes
- Charge current accuracy depends on the sense resistor tolerance, so use a 1% or better part and keep its traces Kelvin-connected.
- Wire the NTC input for JEITA profile control if the pack is charged over temperature.
- Set the input current limit to what the adapter can actually deliver; a limit above the adapter rating causes the input rail to collapse mid-charge.
- Termination current and recharge threshold dominate cycle life in shallow-cycling products.
