6-A Wide-Input Voltage Adjustable Switching Regulator

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 case-less, 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.
