TEXAS INSTRUMENTS PTH04070WAD

The PTH04070WAD is a 1-output 10.8W through hole-mount surface-mount non-isolated input adjustable Switching Regulator that delivers up to 3A of output current. Occupying less PCB area than a standard TO-220 linear regulator IC, the PTH04070W provides output current at a much higher efficiency and with much less power dissipation, thereby eliminating the need for a heat sink. Their small size (0.5 x 0.4 in), high efficiency and low cost makes these modules attractive for a variety of applications. Using state-of-the-art switched-mode power-conversion technology, the PTH04070W can step down to voltages as low as 0.9V from a 5V input bus, with typically less than 1W of power dissipation. The output voltage can be adjusted to any voltage over the range, 0.9 to 3.6V, using a single external resistor. Operating features include an under-voltage lockout (UVLO), ON/OFF inhibit, output overcurrent protection and over-temperature protection.
