Texas Instruments LMZ21700SILT Nano DC/DC Buck Converter Module 0.9-6V Output

Texas Instruments LMZ21700SILT is a nano DC/DC buck converter module offering a compact step-down power solution with an adjustable output of 0.9V to 6V.

The module integrates the inductor into an 8-pin µSIP package, making it straightforward to design into space-constrained applications. It is capable of driving loads up to 650mA and requires only a minimal external component count to operate.

Overview

For basic operation, the module needs only an input capacitor, an output capacitor, a soft-start capacitor, and two resistors. Its miniature 3.5 mm x 3.5 mm x 1.75 mm footprint suits modern, compact electronics. Efficiency of up to 95% helps minimise power loss and heat generation. The listed product dimensions are 3 (width), 2.5 (depth), and 4 (height), with a weight of 0.317 gm.
