DESCRIPTION

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.
