The PTH08080WAS is a 1-output 10W surface-mount non-isolated adjust Miniature Power Module delivers up to 2.25A of output current. The PTH08080W sources output current at a much higher efficiency than a TO-220 linear regulator IC, thereby eliminating the need for a heat sink. Its small size (0.5 x 0.6 in) and flexible operation creates value for a variety of applications. The input voltage range of the PTH08080W is from 4.5 to 18V, allowing operation from either a 5 or 12V input bus. Using state-of-the-art switched-mode power-conversion technology, the PTH08080W can step down to voltages as low as 0.9V from a 5V input bus, with less than 1W of power dissipation. The output voltage can be adjusted to any voltage over the range, 0.9 to 5.5V, using a single external resistor. Operating features include an under-voltage lockout (UVLO), ON/OFF inhibit, overcurrent protection and over-temperature protection.
