Texas Instruments' LMZ20501/02 SIMPLE SWITCHER® Nano Module regulator is an easy-to-use synchronous step-down DC-DC converter capable of driving up to 1 A of load from an input of up to 5.5 V, with exceptional efficiency and output accuracy in a very small solution size. The innovative package contains the regulator and inductor in a small 3.5 mm x 3.5 mm x 1.75 mm volume, thus saving board space and eliminating the time and expense of inductor selection. The LMZ20501 requires only five external components and has a pin-out designed for simple, optimum PCB layout.

The LMZ21700/01 SIMPLE SWITCHER Nano Module is an easy-to-use step-down DC-DC converter capable of driving up to 650 mA (LMZ21700) or 1 A (LMZ21701) load in space-constrained applications. Only an input capacitor, an output capacitor, a softstart capacitor, and two resistors are required for basic operation.
