概要
説明
The RTKA489108DE0000BU evaluation board evaluates the performance of the RAA489108 buck-boost Narrow Output Voltage DC (NVDC) charger.
The RAA489108 is a buck-boost NVDC charger that uses Renesas' advanced R3™ Technology to provide high light-load efficiency, fast transient response, and seamless DCM/CCM transitions for a variety of mobile and industrial applications.
In charge mode, the RAA489108 takes input power from a wide range (3.9V to 30V) of DC power sources (such as conventional AC/DC charger adapters, USB PD ports, and travel adapters) and safely charges battery packs with up to four cells in a series configuration.
The RAA489108 provides serial communication with SMBus/I2C that allows for the programming of critical parameters to deliver a customized solution. The programmable parameters include (but are not limited to) the following: adapter current limit, charger current limit, system voltage setting, and trickle charging current limit.
