Input voltage4.5-36 V
Output 114.4 V / 3 A
IC revision1.0

Description

Lead-acid batteries are widely used in battery-powered devices due to their advantages, such as a stable voltage, low price, simple maintenance, and high reliability. However, there are few chips on the market that are designed specifically for applications that charge lead-acid batteries.This reference design showcases a lead-acid battery charging solution. The solution uses the MP2659, a highly integrated switching charger designed for portable devices with 3-cell to 6-cell series Li-ion or Lipolymer battery packs.

Features

  • Up to 36V Operating Input Voltage
  • 45V Maximum Sustainable Voltage When Not Switching
  • Up to 3A Charge Current
  • 1-Cell, 12V Lead Acid Battery
  • 0.5% Reference Voltage Accuracy
  • Input Current Limit Regulation
