EVALUATION KIT AVAILABLE

MAX16935/MAX16939

36V, 3.5A, 2.2MHz Step-Down Converters

with 28µA Quiescent Current

General Description

Beneﬁts and Features

● Integration and High-Switching Frequency Saves

The MAX16935/MAX16939 are 3.5A current-mode step-

down converters with integrated high-side and low-

side MOSFETs designed to operate with an external

Schottky diode for better efficiency. The low-side MOSFET

enables fixed-frequency forced-PWM (FPWM) operation

under light-load applications. The devices operate with

input voltages from 3.5V to 36V, while using only 28FA

quiescent current at no load. The switching frequency is

resistor programmable from 220kHz to 2.2MHz and can

be synchronized to an external clock. The devices’ output

voltage is available as 3.3V/5V fixed or adjustable from

1V to 10V. The wide input voltage range along with its

ability to operate at 98% duty cycle during undervoltage

transients make the devices ideal for automotive and

industrial applications.

Space

• Integrated 3.5A High-Side Switch

• Low-BOM-Count Current-Mode Control

Architecture

• Fixed Output Voltage with ±2% Accuracy or

Externally Resistor Adjustable (1V to 10V)

• 220kHz to 2.2MHz Switching Frequency with

Three Operation Modes (Skip Mode, Forced

Fixed-Frequency Operation, and External

Frequency Synchronization)

• Automatic LX Slew-Rate Adjustment for Optimum

Eﬃciency Across Operating Frequency Range

● 180° Out-of-Phase Clock Output at SYNCOUT

Enables Cascaded Power Supplies for Increased

Power Output

Under light-load applications, the FSYNC logic input

allows the devices to either operate in skip mode for

reduced current consumption or fixed-frequency FPWM

mode to eliminate frequency variation to minimize

EMI. Fixed-frequency FPWM mode is extremely use-

ful for power supplies designed for RF transceivers

where tight emission control is necessary. Protection

features include cycle-by-cycle current limit and thermal

shutdown with automatic recovery. Additional features

include a power-good monitor to ease power-supply

sequencing and a 180N out-of-phase clock output relative

to the internal oscillator at SYNCOUT to create cascaded

power supplies with multiple devices.

● Spread-Spectrum Frequency Modulation Reduces

EMI Emissions

● Wide Input Voltage Range Supports Automotive

Applications

• 3.5V to 36V Input Voltage Range (42V Tolerant)

• Enable Input Compatible from 3.3V Logic Level

to 42V

● Robust Performance Supports Wide Range of

Automotive Applications

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

• Thermal-Shutdown Protection

• AEC-Q100 Qualiﬁed

The MAX16935/MAX16939 operate over the -40NC

to +125NC automotive temperature range and are

available in 16-pin (5mm x 5mm) TQFN-EP and 16-pin

TSSOP-EP packages.

● Power-Good Output Allows Power-Supply

Sequencing

● Tight Overvoltage Protection Provides Smaller

Applications

● Point-of-Load Applications

Overshoot Voltages (MAX16939)

● Distributed DC Power Systems

● Navigation and Radio Head Units
