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

Application Circuit appear at end of data sheet.
