The ADP3025 is a highly efficient, dual synchronous buck switching regulator controller optimized for wide input voltage range, high conversion efficiency, low shutdown current, and low cost, making it suitable for a wide range of applications, including portable instruments and general-purpose DC/DC converters.
The ADP3025 is a highly efficient, dual synchronous buck switching regulator controller optimized for converting battery or adapter input into supply voltages required in portable products and industrial systems. It features wide input voltage range support from 5.5 V to 25 V and high conversion efficiency greater than 96%.
The device includes two independently programmable output voltages, with options for fixed 3.3 V or 5 V outputs, or adjustable ranges between 800 mV and 6.0 V. Key features include an integrated current sense circuit that eliminates the need for external resistors, a built-in gate drive boost circuit for driving high-side N-channel MOSFETs, and extensive protection functions such as short-circuit protection, UVLO, and output undervoltage/overvoltage protection.
