Product Details
The MAX77845 Evaluation Kit (EV kit) is a fully assembled and tested printed circuit board (PCB) designed to demonstrate the capabilities of the MAX77845, a high-efficiency, high-performance buck-boost regulator with a 5A switching current. The integrated circuit (IC) supports an input voltage range of 2.5V to 16V and provides a dynamically adjustable output voltage between 3V and 15V.
By default, the EV kit is configured with internal feedback and a start-up output voltage of 5V. Alternative start-up voltages can be achieved by using external feedback resistors or by enabling the I2C block using the BIASEN pin to adjust the output voltage before activation. The output voltage can also be modified dynamically through the I2C serial interface.
The kit includes I/O pins for the I2C interface, enable function, SYNC, and interrupt/power-OK indicators. Key parameters such as the I2C subordinate address, switching current limit, switching frequency, and feedback configuration can be adjusted by changing the RSEL resistor (R9) or the variable resistor (R8). The MAXUSB_INTERFACE# enables communication with Microsoft Windows®-based software, offering both a user-friendly graphical interface (ACE) and a detailed register-level interface to access all features of the IC. The EV kit is compatible with all versions of the MAX77845 WLP IC.
