Description

General part information

MAX16993 Series

The MAX16993 power-management integrated circuit (PMIC) is a 2.1MHz, multichannel, DC-DC converter designed for automotive applications. The device integrates three supplies in a small footprint. The device includes one high-voltage step-down controller (OUT1) designed to run directly from a car battery and two low-voltage step-down converters (OUT2/OUT3) cascaded from OUT1. Under no-load conditions, the MAX16993 consumes only 30µA of quiescent current, making it ideal for automotive applications.The high-voltage synchronous step-down DC-DC controller (OUT1) operates from a voltage up to 36V continuous and is protected from load-dump transients up to 42V. There is a pin-selectable frequency option of either 2.1MHz or a factory-set frequency for 1.05MHz, 525kHz, 420kHz, or 350kHz. The low-voltage, synchronous step-down DC-DC converters run directly from OUT1 and can supply output currents up to 3A.The device provides a spread-spectrum enable input (SSEN) to provide quick improvement in electromagnetic interference when needed. There is also a SYNC input for providing an input to synchronize to an external clock source (see theSelector Guidein the full data sheet). The device includes overtemperature shutdown and overcurrent limiting. The device also includes individual active-low RESET_ outputs and individual enable inputs. The active-low RESET_ outputs provide voltage monitoring for all output channels.The MAX16993 is available in a 32-pin TQFN/side-wettable QFND-EP package and is specified for operation over the -40°C to +125°C automotive temperature range.ApplicationsAutomotiveIndustrial
