Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The MAX77541AAFG is a high-efficiency buck converter with two 3A switching phases for single Li+ battery and 5VDC systems. It uses an adaptive COT (constant on-time) current-mode control architecture, and the two 3A switching phases can be configured as one (2Φ, 6A) or two (1Φ, 3A each) outputs. The output voltage is preset via resistors and can be further adjusted via an I2C compatible interface. With 91% peak efficiency, low quiescent current and compact solution size, they are ideally suited for battery-powered, space-compact applications.
