DESCRIPTION  
The PTN78020 is a series of high-efficiency, step-down integrated switching regulators (ISRs), that represent the  
third generation in the evolution of high-performance power modules designed for industrial use. The wide-input  
voltage range makes these modules suitable for a variety of applications that operate off 12–V, 24–V, and 28–V  
dc power. In new designs they should be considered in place of the PT6620, PT6650, PT6680, and PT6880  
series of single in-line pin (SIP) products. The PTN78020 is smaller and lighter than its predecessors, and has  
either similar or improved electrical performance characteristics. The caseless, double-sided package has  
excellent thermal characteristics, and is compatible with TI's roadmap for RoHS and lead-free compliance.  
Operating from a wide-input voltage range, the PTN78020 provides high-efficiency, step-down voltage  
conversion for loads of up to 6 A. The output voltage is set using a single, external resistor. The PTN78020W  
may be set to any value within the range, 2.5 V to 12.6 V, and the PTN78020H from 11.85 V to 22 V. The output  
voltage of the PTN78020W can be as little as 2 V lower than the input, allowing operation down to 7 V, with an  
output voltage of 5 V. The output voltage of the PTN78020H can be as little as 3 V lower than the input, allowing  
operation down to 15 V, with an output voltage of 12 V.  
The PTN78020 has undervoltage lockout, an integral on/off inhibit, and includes an output current limit and  
overtemperature protection.
