Overview

TopologyBuck Converter
Input voltage10.8-13.2 V
IC revision1.20

Description

This document describes the use of ZMDI’s ZSPM15xx-KIT01 for evaluating DC/DC point-of-load (POL) applica-tions and provides additional kit information, including the circuit diagram and board layout. The kit incorporates ZMDI’s ZSPM15xx digital PWM controller IC and a ZSPM9060 DrMOS to form a “smart” buck converter (a.k.a. step-down DC-to-DC converter).Note: The ZSPM15xx Family includes the ZSPM1501, ZSPM1502, ZSPM1503, ZSPM1504, ZSPM1505, ZSPM1506, ZSPM1507, ZSPM1508, ZSPM1509, ZSPM1511, ZSPM1512, and ZSPM1513. Unless otherwise noted, all references to the ZSPM15xx apply to all these products.The ZSPM15xx-KIT01 Evaluation Kit hardware functions as a fixed-voltage self-starting autonomous DC/DC converter, which requires no software or subsequent programming.
