Overview

Description

ZSPM15xx family ICs are controllers designed for high-current, non-isolated DC/DC step-down point of load (POL) converters. For ease of use, the ZSPM15xx is factory pre-configured for industry standard output voltages and currents enabling fast time-to-market. The ZSPM1508 provides a fixed output voltage of 3.30V with a load current range up to 15A using the recommended inductor value of 2200nH.

The ZSPM15xx has a digital control loop that is optimized for maximum stability as well as load step and steady-state performance. ZSPM15xx family ICs have a rich set of integrated fault protection features including over-voltage/under-voltage, output over-current, and over-temperature protections. 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 IDT's DrMOS devices. Reference designs and application instructions enable a high performance turnkey solution without extensive engineering development.
