MAX8566ETJ+

The MAX8566ETJ+ is a high-efficiency switching regulator designed by Analog Devices / Maxim Integrated. It delivers up to 10A of load current with an adjustable output voltage ranging from 0.6V to (0.87 x VIN). The device operates from input supplies of 2.3V to 3.6V, making it suitable for point-of-load applications.

This regulator operates in PWM mode with a programmable switching frequency between 250kHz and 2.4MHz, which can be synchronized to an external clock. The high operating frequency minimizes the size of external components and allows for all-ceramic-capacitor designs. The total output-voltage set error is less than ±1% over load, line, and temperature.

The MAX8566ETJ+ features internal 8mΩ n-channel MOSFETs for both high- and low-side switches, maintaining high efficiency. It employs a voltage-mode control architecture with a high-bandwidth error amplifier (>10MHz) for fast transient response. An adjustable soft-start time is provided for flexibility in minimizing input startup inrush current. The device includes a power-good output signal and a SYNCOUT output for synchronizing a second regulator.

Available in a 32-pin TQFN package, the MAX8566ETJ+ and its required external components can fit into a compact footprint of less than 0.80in². It is ideal for applications such as ASIC/CPU/DSP core voltages, POL power supplies, and DDR power supplies.
