Overview
The PTH08080W, produced by Texas Instruments, is a highly integrated, low-cost switching regulator module designed to deliver up to 2.25 A of output current. This module is notable for its high efficiency, which exceeds that of traditional TO-220 linear regulator ICs, thereby eliminating the need for a heat sink. With a compact size of 0.5 × 0.6 inches, it offers flexible operation suitable for various applications. The module supports an input voltage range of 4.5 V to 18 V, allowing it to operate from either a 5-V or 12-V input bus, and can step down to voltages as low as 0.9 V with minimal power dissipation.
