EVALUATION KIT AVAILABLE

MAX16932/MAX16933

2.2MHz, 36V, Dual Buck

with 20µA Quiescent Current

General Description

Beneﬁts and Features

● Meets Stringent OEM Module Power Consumption

The MAX16932/MAX16933 offer two high-voltage,

synchronous step-down controllers that use only 20µA of

quiescent current with no load. They operate with an input

voltage supply from 3.5V to 42V and can operate in drop-

out condition by running at 95% duty cycle. The devices

are intended for applications with mid- to high-power

requirements and requiring two independently controlled

output supplies, such as automotive applications.

and Performance Specifications

• 20µA Quiescent Current in Skip Mode

• ±1% Output-Voltage Accuracy: 5.0V/3.3V Fixed or

Adjustable Between 1V and 10V

● Enables Crank-Ready Designs

• Wide Input Supply Range from 3.5V to 36V

● EMI Reduction Features Reduce Interference with

Sensitive Radio Bands without Sacrificing Wide Input

Voltage Range

The MAX16932/MAX16933 step-down controllers oper-

ate 180° out-of-phase for reduced input ripple. The

devices also operate with switching frequencies up to

2.2MHz to allow use of small external components and

to guarantee no AM band interference. The FSYNC input

programmability enables three frequency modes for opti-

mized performance: forced fixed-frequency operation,

skip mode with ultra-low quiescent current (20µA), and

synchronization to an external clock. The devices provide

a spread-spectrum option to minimize EMI interference.

• 50ns (typ) Minimum On-Time Guarantees Skip-

Free Operation for 3.3V Output from Car Battery

at 2.2MHz

• Spread-Spectrum Option

• Frequency-Synchronization Input

• Resistor-Programmable Frequency Between

200kHz and 2.2MHz

● Integration and Thermally Enhanced Packages Save

Board Space and Cost

The devices also feature a power-OK monitor and over-

voltage and undervoltage lockout. Protection features

include cycle-by-cycle current limit and thermal shutdown.

• Dual, 2MHz Step-Down Controllers

• 180° Out-of-Phase Operation

• Current-Mode Controllers with Forced-Continuous

and Skip Modes

• Thermally Enhanced 28-Pin TQFN-EP Package

The devices are available in a 28-pin TQFN-EP package

and are specified for operation over the -40°C to +125°C

automotive temperature range.

● Protection Features Improve System Reliability

• Supply Overvoltage and Undervoltage Lockout

• Overtemperature and Short-Circuit Protection

Ordering Information and Selector Guide appears at end of

data sheet.

Applications

● POL Applications for Automotive Power

● Distributed DC Power Systems

● Navigation and Radio Head Units
