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.
