Overview

The OKL-T/3-W12N-C is a non-isolated Point-of-Load (PoL) DC-DC converter module designed for surface mount applications. It delivers up to 3A of output current with a programmable output voltage ranging from 0.591V to 5.5V from a wide 4.5V to 14V input range. Built on a synchronous buck topology, it achieves up to 93% efficiency in a compact 12.2mm square footprint.

Why Choose This Part

The module features an inspectable Land Grid Array (iLGA) package which simplifies visual inspection of solder joints in high-reliability applications. It includes comprehensive protection circuitry such as under-voltage lockout, short circuit protection, and thermal shutdown, while maintaining a very high 93% efficiency to minimize heat dissipation.

Applications

Distributed Power Architectures
Providing localized voltage regulation for FPGAs, ASICs, and processors on complex multi-rail boards.
Telecommunications Equipment
Efficiently stepping down intermediate bus voltages to logic-level rails in networking hardware.
Computing and Servers
Serving as a high-density power solution for industrial computing and high-performance server motherboards.

Getting Started

To implement this module, design the PCB layout following the manufacturer's recommended land pattern for the 12-SMD iLGA package. Output voltage is set using a single external resistor connected to the trim pin according to the formula provided in the datasheet. Ensure adequate input and output capacitance is placed close to the module pins to minimize ripple and noise.
