Analog Devices Inc. MAX77960/MAX77961 USB-C™ Buck-Boost Chargers
Analog Devices Inc. MAX77960/MAX7761 USB-C™ Buck-Boost Chargers are high-performance wide input 3A or 6A chargers with Smart Power Selector™. The chargers operate as a reverse buck converter without an additional inductor. This allows the ICs to power USB on-the-go (OTG) accessories. The devices integrate low-loss power switches and provide high efficiency. MAX77960/MAX7761 also provides low heat, fast battery charging, and a true load disconnect. An adjustable output current limit protects it. The devices are highly flexible and programmable through the I2C configuration or autonomously through a resistor configuration.
