Renesas ZSPM1502 | Demoboard ZSPM15xx-KIT01

Evaluation Kit for the ZSPM15xx True-Digital PWM Controller

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).

The ZSPM15xx-KIT01 Evaluation Kit hardware functions as a fixed-voltage self-starting autonomous DC/DC converter, which requires no software or subsequent programming.
