TIDA-010042

Design files

Overview

This reference design is a Maximum Power Point Tracking (MPPT) solar charge controller for 12V and 24V 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 15V to 60V solar panel modules, 12V or 24V batteries, and providing upwards of 16A 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

98.5% efficiency in 12V systems and 98.8% efficiency in 24V systems
Wide input voltage range of 15V to 60V
Flexible design supports 12V and 24V battery voltages
High-rated output current of 16A
Battery reverse polarity, over-charge and over-discharge protections
System overtemperature detection capability
Small board form factor of 83mm × 82mm × 26mm
