EVALUATION KIT AVAILABLE  
MAX16936/MAX16938  
36V, 220kHz to 2.2MHz Step-Down Converters  
with 28µA Quiescent Current  
General Description  
Benefits and Features  
Integration and High-Switching Frequency Saves  
The MAX16936/MAX16938 are 2.5A 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 28µA  
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 5V/3.3V 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 2.5A High-Side Switch  
• Low-BOM-Count Current-Mode Control  
Architecture  
• Fixed Output Voltage with ±2% Accuracy (5V/3.3V)  
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 useful 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 180º out-of-phase clock output relative to the inter-  
nal 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  
• Enable Input Compatible from 3.3V Logic Level  
to 42V  
Robust Performance Supports Wide Range of  
Automotive Applications  
• 42V Load-Dump Protection  
• -40°C to +125°C Automotive Temperature Range  
• Thermal-Shutdown Protection  
AEC-Q100 Qualified  
The MAX16936/MAX16938 operate over the -40ºC to  
+125ºC automotive temperature range and are available  
in 16-pin TSSOP-EP and 5mm x 5mm, 16-pin TQFN-EP  
packages.  
Power-Good Output Allows Power-Supply  
Sequencing  
Applications  
Point-of-Load Applications  
Distributed DC Power Systems
