SIMPLE SWITCHER® 3V to 17V, 1A High Density Nano Module  - LMZ21701

LMZ21701 (ACTIVE)

SIMPLE SWITCHER® 3V to 17V, 1A High Density Nano Module

 

Description

The LMZ21701 SIMPLE SWITCHER Nano Module is an easy-to-use step-down DC-DC solution capable of driving up to 1000 mA load in space-constrained applications. Only an input capacitor, an output capacitor, a softstart capacitor, and two resistors are required for basic operation.

Quick links to typical applications: VOUT = 1.2 V, VOUT = 1.8 V, VOUT = 2.5 V, VOUT = 3.3 V, VOUT = 5.0 V
