Introduction
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. The device includes overtemperature shutdown and overcurrent limiting. The device also includes individual RESET_ outputs and individual enable inputs. The individual 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℃ to +125℃ automotive temperature range.
