MAX16993

Step-Down Controller with

Dual 2.1MHz Step-Down DC-DC Converters

General Description

Beneﬁts and Features

● High-Efficiency Voltage DC-DC Controller Saves

The MAX16993 power-management integrated circuit

(PMIC) is a 2.1MHz, multichannel, DC-DC convert-

er 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.

Power

• 3.5V to 36V Operating Supply Voltage

• Output Voltage: Pin Selectable, Fixed, or

Resistor-Divider Adjustable

• 350kHz to 2.1MHz Operation

• 30μAꢀQuiescentꢀCurrentꢀwithꢀDC-DCꢀ

Controller Enabled

● Dual 2.1MHz DC-DC Converters with Integrated

FETs Save Space

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.

• OUT2 and OUT3 are Cascaded from OUT1,

Improving Efficiency

• 3A Integrated FETs

• 0.8V to 3.95V Output Voltage

• Fixed or Resistor-Divider-Adjustable Output Voltage

• 180° Out-of-Phase Operation

• Robust for the Automotive Environment

● Current-Mode Architecture with Forced-PWM and

Skip Modes of Operation

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 the Selector Guide).

The device includes overtemperature shutdown and

overcurrent limiting. The device also includes indi-

vidual RESET_ outputs and individual enable inputs.

The individual RESET_ outputs provide voltage

monitoring for all output channels.

• Frequency Synchronization Input/Output Reduces

System Noise

• Individual Enable Inputs and RESET_ Outputs

• Overtemperature and Short-Circuit Protection

• AECQ-100ꢀQualiﬁed

• 32-Pin TQFN-EP (5mm x 5mm x 0.75mm) and

Side-Wettable QFND-EP (5mm x 5mm x 0.8mm)

• -40°C to +125°C Operating Temperature Range

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.

Ordering Information and Selector Guide appear at end of

data sheet.
