Analog Devices / Maxim Integrated MAX17645 Synchronous Step-Down DC-DC Converters
Analog Devices MAX17645 Synchronous Step-Down DC-DC Converters feature integrated FETS and compensation. These converters are housed in a small solution size. The small size allows fewer components and helps to reduce overall design costs for the system. Analog Devices MAX17645 Synchronous Step-Down DC-DC Converters operate in a -40°C to +125°C ambient temperature range.
