The Analog Devices Inc./Maxim Integrated MAX5038AEAI18 is a highly efficient 2-output, synchronous buck controller designed for step-down DC-DC conversion. Operating with an input voltage range of 4.75V to 28V, this device features selectable switching frequencies of 250kHz and 500kHz, enabling optimization for efficiency or size. The MAX5038AEAI18 provides independent control for two positive output voltage rails, each capable of driving an external P-channel MOSFET for the high-side switch. Its synchronous rectification topology ensures high efficiency, making it suitable for power management in applications such as point-of-load converters, battery-powered systems, and general-purpose power supplies. The controller includes an enable pin for power sequencing and shutdown capabilities. It is packaged in a 28-SSOP (0.209", 5.30mm Width) surface-mount configuration and operates within an ambient temperature range of -40°C to 85°C.
