图1LMZ31520内部结构图
TheLMZ31520 SIMPLE SWITCHER® power module is an easy-to-use integrated power solution that combines a 20-A DC/DC converter with power MOSFETs, a shielded inductor, and passives into a low profile, QFN package.

TheLMZ31520 relies on a precision trimmed 0.6 V reference for the feedback voltage regulation and operates by regulating the valley of the voltage ripple appearing at the VADJ pin. The voltage ripple is a function of the input voltage and the output voltage, therefore the RSET resistor will change based on the input voltage.
