DESCRIPTION  
The PTV12020 series of nonisolated power modules are part of a new class of complete dc/dc switching  
regulator modules from Texas Instruments. These regulators combine high performance with double-sided,  
surface mount construction to give designers the flexibility to power the most complex multiprocessor digital  
systems using off-the-shelf catalog parts.  
The PTV12020 series is produced in a 12-pin, single in-line pin (SIP) package. The SIP footprint minimizes board  
space, and offers an alternate package option for space conscious applications. Operating from a 12-V input bus,  
the series provides step-down conversion to a wide range of output voltages, at up to 16 A of output current. The  
output voltage of the W-suffix parts can be set to any value over the range of 1.2 V to 5.5 V. The L-suffix parts  
have an adjustment range of 0.8 V to 1.8 V. The output voltage is set using a single external resistor.  
This series includes Auto-Track™. Auto-Track™ simplifies the task of supply-voltage sequencing in a power  
system by enabling the output voltage of multiple modules to accurately track each other, or any external voltage,  
during power up and power down.  
Other operating features include an on/off inhibit, and the ability to start up into an existing output voltage or  
prebias. For improved load regulation, an output voltage sense is provided. A nonlatching overcurrent trip and  
overtemperature shutdown protects against load faults.  
Target applications include complex multivoltage, multiprocessor systems that incorporate the industry's  
high-speed DSPs, microprocessors, and bus drivers.  
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas  
Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
