ISL9237EVAL2Z Datasheet PDF - Renesas Electronics

●The ISL9237EVAL2Z is a buck-boost charger evaluation board. The ISL9237EVAL2Z evaluation board is designed to demonstrate the performance of the ISL9237HRZ IC. The ISL9237 is a buck-boost narrow output voltage DC (NVDC) charger utilizing intersil"s 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. The ISL9237 has serial communication via SMBus/I2C that allows programming of many critical parameters to deliver a customized solution. A majority of the features of the ISL9237, such as adjustable output voltage, on-the-go (OTG) mode, trickle charging mode for depleted battery and system power monitor at buck, boost and buck-boost modes are available on this evaluation board.
