LMZ21700 features: integrated sensor; adjustable output voltage; adjustable soft start function; boot into pre-biased load LMZ21700 typical application range: space-constrained applications; LDO replacement LMZ21700 reference design application circuit: Figure 1 Internal structure of the LMX21700 The LMZ21700 SIMPLE SWITCHER® Nano Module is an easy-to-use step-down DC-DC solution capable of driving up to 650 mA load in space-constrained applications. Only an input capacitor, an output capacitor, a softstart capacitor, and two Resistors are required for basic operation. Figure 2LMZ21700 reference design The LMZ21700 architecture uses Pulse Width Modulation (PWM) mode for medium and heavy load requirements and Power Save Mode (PSM) at light loads for high efficiency. In PWM mode the switching frequency is controlled over the input voltage range.

It is used to drive machinery or home appliances. Since AC Power Cord is output of high voltage electric power, there is a risk of electric shock injury, therefore, All the AC power cord must comply with safety standard to produce. DC (direct Current) power cord is used to the applicance with lower voltage mostly, so safety requirement is less stringent.
