PTN78060W

The PTN78060W 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 PTN78060W 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 PTN78060W 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 of 7 V to 36 V, the PTN78060W 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 adjust range of the W-suffix part is 2.5 V to 12.6 V. The output voltage can be as little as 2 V lower than the input, allowing operation down to 7 V, with an output voltage of 5 V. Other features include an integral on/off inhibit. An output voltage sense ensures tight load regulation.

The PTN78060W is suited to a wide variety of general-purpose industrial applications that operate off 12-V, 24-V, or 28-V dc power.
