MAX77845EVKIT

产品详情

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 R_SEL 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.
