The PTN78000WAH from Texas Instruments is an adjustable switching regulator module. 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. PTN78000WAH may be set to any value within the range of 2.5V to 12.6V. Output voltage of the PTN78000WAH can be as little as 2V lower than the input allowing operation down to 7V with an output voltage of 5V.
