Overview

This reference design is a Maximum Power Point Tracking (MPPT) solar charge controller for 12-V and 24-V batteries that can be used as a power optimizer in the future. This compact reference design targets small- and medium-power solar charger designs and is capable of operating with 15-V to 60-V solar panel modules, 12-V or 24-V batteries, and providing upwards of 16-A output current. The design uses a buck converter to step down the panel voltage to the battery voltage. The half-bridge power stage with internal integrated drivers is controlled by a microcontroller unit (MCU), which calculates the maximum power point using the perturb and observe method. The solar MPPT charge controller is created with real-world considerations, including reverse battery protection, software programmable alarms and indications, and surge and ESD protection.

Features
  • 98.3% efficiency in 12-V systems and 98.5% efficiency in 24-V systems
  • Wide input voltage range of 15 V to 60 V
  • Flexible design supports 12-V and 24-V battery voltages
  • High-rated output current of 16 A
  • Battery reverse polarity, over-charge and over-discharge protections
  • System overtemperature and ambient light detection capabilities
  • Small board form factor of 95 mm × 68.2 mm × 25 mm
