Product Details

The MAX16712 is a dual-output, fully integrated, highly efficient, step-down DC-DC switching regulator. The device operates from 2.7V to 16V input supplies, and each output can be regulated from 0.5V to 5.8V. The IC delivers up to 6A of load current per output. The two outputs can be connected in parallel as a single-output, dual-phase regulator that supports up to 12A load current.

The switching frequency of the device can be configured from 500kHz to 2.0MHz and provides the capability of optimizing the design in terms of solution size and performance.

The MAX16712 utilizes fixed-frequency, current-mode control with internal compensation. The dual-switching regulators operate 180° out-of-phase. The IC features an advanced modulation scheme (AMS) and selectable discontinuous current mode (DCM) operation to provide improved performance. Operation settings and configurable features can also be selected by connecting a pin-strap resistor from PGM0 pin to ground.

The MAX16712 has an internal 1.8V LDO output to power the gate drives (VCC) and internal circuitry (AVDD).

The MAX16712 integrates multiple protections including positive and negative overcurrent protection, output overvoltage protection and overtemperature protection to ensure robust design.

The device is available in a compact 2.2mm x 3.5mm wafer-level package (WLP). It supports -40°C to +125°C junction temperature operation.
