3-A, 3.3/5-V Input Adjustable Switching Regulator

The PTH04070W is a highly integrated, low-cost Switching Regulator module that delivers up to 3 A 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 0.4 in), high efficiency, and low cost makes these modules attractive for a variety of applications.
The input voltage range of the PTH04070W is from 3 V to 5.5 V, allowing operation from either a 3.3-V or 5-V input bus. Using state-of-the-art switched-mode power-conversion technology, the PTH04070W CAN step down to voltages as low as 0.9 V from a 5-V input bus, with typically less than 1 W of power dissipation. The output voltage CAN be adjusted to any voltage over the range, 0.9 V to 3.6 V, using a single external resistor. Operating features include an undervoltage lockout (UVLO), on/off inhibit, output overcurrent protection, and overtemperature protection. Target applications include telecommunications, test and measurement applications, and high-end consumer products. The modules are available in both through-hole and surface-mount package options, including tape and reel.
