MAX15066EVKIT+: 1.8V @ 4A, 4.5 ~ 16V in

The MAX15066 evaluation kit (EV kit) provides a proven design to evaluate the MAX15066 high-efficiency, 4A, step-down regulator with integrated switches. The EV kit is preset for 1.8V output at load currents up to 4A from a 4.5V to 16V input supply.

The MAX15066/MAX15166 current-mode, synchronous, DC-DC buck converters deliver an output current up to 4A with high efficiency. The devices operate from an input voltage of 4.5V to 16V and provide an adjustable output voltage from 0.606V to 90% of the input voltage.

The devices are ideal for distributed power systems, notebook computers, non-portable consumer applications, and pre-regulation applications.

The devices feature a PWM mode operation with an internally fixed switching frequency of 500 kHz (MAX15066) and 350 kHz (MAX15166) capable of 90% maximum duty cycle. The devices automatically enter skip mode at light loads. The current-mode control architecture simplifies compensation design and ensures a cycle-by-cycle current limit and fast response to line and load transients. A high gain transconductance error amplifier allows flexibility in setting the external compensation, simplifying the design and allowing for an all-ceramic design.
