PMP10921 Reference Design

Texas Instruments

14V-24Vdc Input Voltage: 3-series Cell Li-Ion Battery Charger Reference Design


The PMP10921 reference design uses the BQ24600 Li-Ion synchronous buck controller to charge up to three series cells. It is designed to charge the cells at 0.372A: but can charge at higher currents by changing one resistor. The board area is less than 20mm x 20mm.

  • Greater than 90% efficiency at 14VinInternal loop compensationSmall board area (20mm x 20mm)Highly integrated controller with wide operating range
  • Vacuum robot
  • Robotic lawn mower
  • Humanoid
