EVALUATION KIT AVAILABLE  
MAX16990/MAX16992  
36V, 2.5MHz Automotive Boost/  
SEPIC Controllers  
General Description  
Benefits and Features  
Minimized Radio Interference with 2.5MHz Switching  
The MAX16990/MAX16992 are high-performance,  
current-mode PWM controllers with 4μA (typ) shut-  
down current for wide input voltage range boost/SEPIC  
converters. The 4.5V to 36V input operating volt-  
age range makes these devices ideal in automotive  
applications such as for front-end “preboost” or “SEPIC”  
power supplies and for the first boost stage in high-  
power LED lighting applications. An internal low-dropout  
regulator (PVL regulator) with a 5V output voltage  
enables the MAX16990/MAX16992 to operate directly  
from an automotive battery input. The input operating  
range can be extended to as low as 2.5V when the  
converter output is applied to the SUP input.  
Frequency Above the AM Radio Band  
Space-Efficient Solution Design with Minimized  
External Components  
• 100kHz to 1MHz (MAX16990) and 1MHz to  
2.5MHz (MAX16992) Switching-Frequency Ranges  
• 12-Pin TQFN (3mm x 3mm) and 10-Pin μMAX  
Packages  
Spread Spectrum Simplifies EMI Management Design  
Flexibility with Available Configurations for Boost,  
SEPIC, and Multiphase Applications  
• Adjustable Slope Compensation  
• Current-Mode Control  
• Internal Soft-Start (9ms)  
There are multiple versions of the devices offering one  
or more of the following functions: a synchronization  
output (SYNCO) for two-phase operation, an overvoltage  
protection function using a separate input pin (OVP), and  
a reference input pin (REFIN) to allow on-the-fly output  
voltage adjustment.  
Protection Features Support Robust Automotive  
Applications  
• Operating Voltage Range Down to 4.5V (2.5V or  
Lower in Bootstrapped Mode), Immune to  
Load-Dump Transient Voltages Up to 42V  
• PGOOD Output and Hiccup Mode for Enhanced  
System Protection  
• Overtemperature Shutdown  
• -40°C to +125°C Operation  
The MAX16990 and MAX16992 operate in different  
frequency ranges. All versions can be synchronized to  
an external master clock using the FSET/SYNC input.  
In addition, the MAX16990/MAX16992 have a factory-  
programmable spread-spectrum option. Both devices  
are available in compact 12-pin TQFN and 10-pin µMAX®  
packages.
