PTH04070W - Texas Instruments

PTH04070W 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.
