Overview

TopologyBuck Converter
Input voltage10.8-13.2 V
IC revision2.2

Description

ZSPM15xx family ICs are controllers designed for high-current, non-isolated DC/DC step-down point of load (POL) converters. The ZSPM15xx has a digitalcontrol loop that is optimized for maximum stability as well as load step and steady-state performance. ZSPM15xx family ICs have a rich set of integratedfault protection features including over-voltage under-voltage, output over-current, and over-temperature protections. To facilitate ease of use, theZSPM15xx is pre-programmed and available for common output voltages. To provide flexibility for the end-customer, the over-current protection threshold and the control loop compensation are selectable by the end-customer to match a number of selected power stages. ZSPM15xx family ICs have been optimized for maximum efficiency when used with ZMDI’s DrMOSdevices. Reference designs and application instructions enable a high performance turnkey solution without extensive engineering development.
