SLTS229B – NOVEMBER 2004 – REVISED JUNE 2009 3-A, WIDE-INPUT ADJUSTABLE SWITCHING REGULATOR • General-Purpose, Industrial Controls, • 3-A Output Current HVAC Systems • Wide-Input Voltage • Test and Measurement, (7 V to 36 V) / (15 V to 36 V) Medical Instrumentation • Wide-Output Voltage Adjust • AC/DC Adaptors, Vehicles, (2.5 V to 12.6 V) / (11.85 V to 22 V) Marine, and Avionics • High Efficiency (Up to 96%) • On/Off Inhibit • Under-Voltage Lockout • Output Current Limit • Overtemperature Shutdown • Operating Temperature: -40°C to 85°C • Surface Mount Package Available The PTN78060 is a series of high-efficiency, step-down integrated switching regulators (ISR), that represent the third generation in the evolution of the popular (PT)78ST200, 78ST300, (PT)78HT200, and 78HT300 series of products. In new designs, the PTN78060 series may also be considered in place of the PT6200, PT6210, and PT6300 series of single in-line pin (SIP) products. In all cases, the PTN78060 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 PTN78060 provides high-efficiency, step-down voltage conversion for loads of up to 3 A. The output voltage can be set to any value over a wide adjustment range using a single external resistor. The PTN78060W may be set to any value within the range, 2.5 V to 12.6 V, and the PTN78060H from 11.85 V to 22 V. The output voltage of the PTN78060W 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 PTN78060H 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 PTN78060 has undervoltage lockout, an integral on/off inhibit, and includes an output current limit and overtemperature protection. It is well suited to a wide variety of general-purpose applications that operate off 12-V, 24-V, or 28-V DC power. 1 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.
