The Analog Devices MAX15046BAEE+T is a high-performance synchronous buck controller designed for step-down power conversion. It accepts an input voltage range of 4.5V to 40V and can generate adjustable output voltages from 0.85 times the input voltage down to 0.6V, supporting high output currents up to 25A.
This controller features an adjustable switching frequency from 100kHz to 1MHz, allowing for optimization of component size and efficiency. It incorporates adaptive synchronous rectification, eliminating the need for an external Schottky diode. The device also utilizes the on-resistance of external low-side MOSFETs for current sensing, removing the requirement for a dedicated current-sense resistor and providing protection against output overloads and short-circuit faults through hiccup-mode current limit.
Additional features include monotonic startup into prebiased outputs, internal digital soft-start, a power-good output, and an enable input. Protection mechanisms include sink-mode current limit and thermal shutdown. The MAX15046BAEE+T is available in a 16-pin QSOP-EP package and operates over an industrial temperature range of -40°C to 125°C.
Applications for this controller include industrial power supplies, telecom power supplies, and base stations.
