This datasheet details the specifications and application information for the Analog Devices ADP3025, a high-efficiency dual synchronous buck switching…
The ADP3025 is a highly efficient, dual output power supply controller optimized for converting battery or adapter input into required supply voltages. It features two independently programmable outputs with fixed options of 3.3 V and 5 V, or adjustable ranges from 800 mV to 6.0 V.
The device utilizes voltage mode PWM with input feed-forward for fast line transient response and includes an integrated current sense circuit that eliminates the need for external resistors. It operates over a wide input voltage range of 5.5 V to 25 V and offers extensive protection functions, including short-circuit, UVLO, and output undervoltage/overvoltage protection.
