DESCRIPTION
The PTN78060A is a series of high-efficiency, buck-boost, integrated switching regulators (ISR), that represent
the third generation in the evolution of the (PT)78NR100 series of products. In new designs, the PTN78060A
series should also be considered in place of the PT6640 series of single in-line pin (SIP) products. In all cases,
the PTN78060A 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 9 V to 29 V, the PTN78060A provides high-efficiency,
positive-to-negative 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 is –15 V to –3 V.
The PTN78060A is suited to a wide variety of general-purpose industrial applications that operate off 12-V, 24-V,
or tightly regulated 28-V dc power.

(1) See the Application Information section for capacitor recommendations
(2) R_SET is required to adjust the output voltage lower than -3 V. See the Application Information section for values.
(3) For reduced V_O ripple and noise, a ceramic capacitor is suggested.
