Overview

The FS1406-1000-AS is a compact, non-isolated micro-POL (Point of Load) digital DC-DC converter from TDK's FS series. It integrates the inductor and PWM controller into a tiny 3.3mm x 3.3mm x 1.5mm package, capable of delivering up to 6A of output current from a 4.5V to 16V input. The device features an I2C interface for digital configuration and monitoring of power parameters.

Why Choose This Part

The FS1406-1000-AS offers an exceptionally high power density by integrating the inductor within the silicon package, reducing the total solution footprint. It provides 0.5 percent output voltage accuracy and includes advanced protection features like thermally compensated over-current protection and digital I2C programmability for system-level flexibility.

Applications

High-Density Server Boards
Providing localized power for high-performance processors and ASICs where PCB real estate is extremely limited.
FPGA Core Power
Supplying the low-voltage, high-current core rails required by modern FPGAs with high accuracy requirements.
Network Switches and Routers
Efficient point-of-load regulation for telecommunications infrastructure equipment.
Optical Transceiver Modules
Small footprint regulation within pluggable optical modules that require high power density.

Getting Started

To evaluate this component, use the TDK FS1406 evaluation board which allows for direct testing of the I2C interface and thermal performance. Design-in requires careful attention to the 17-SMD module land pattern and thermal vias to manage heat dissipation at the full 6A load. Digital configuration can be performed via any standard I2C controller to adjust output voltage and protection thresholds.
