PTN78000WAS

The PTN78000WAS is a 1-output 22.5W surface-mount non-isolated adjustable step-down Integrated Switching Regulator represent the third generation in the evolution of the popular 78ST100 series of products. The PTN78000 is smaller and lighter than its predecessors and has either similar or improved electrical performance characteristics. Operating from a wide-input voltage range, the PTN78000 provides high-efficiency, step-down voltage conversion for loads of up to 1.5A. The output voltage is set using a single external resistor. The PTN78000W may be set to any value within the range, 2.5 to 12.6V and the PTN78000H from 11.85 to 22V. The output voltage of the PTN78000W can be as little as 2V lower than the input, allowing operation down to 7V, with an output voltage of 5V. The output voltage of the PTN78000H can be as little as 3V lower than the input, allowing operation down to 15V, with an output voltage of 12V. The PTN78000 has under-voltage lockout and an integral ON/OFF inhibit.

• Wide-input voltage (7 to 36V)/(15 to 36V)
• High efficiency (up to 95%)
• ON/OFF inhibit
• Under-voltage lockout
• Output current limit
• Over-temperature shutdown
