DESCRIPTION

The PTH08080W is a highly integrated, low-cost switching regulator module that delivers up to 2.25 A 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 × 0.6 in) and flexible operation creates value for a

variety of applications.

The input voltage range of the PTH08080W is from 4.5 V to 18 V, allowing operation from either a 5-V or 12-V

input bus. Using state-of-the-art switched-mode power-conversion technology, the PTH08080W can step down to

voltages as low as 0.9 V from a 5-V input bus, with less than 1 W of power dissipation. The output voltage can

be adjusted to any voltage over the range, 0.9 V to 5.5 V, using a single external resistor. Operating features

include an undervoltage lockout (UVLO), on/off inhibit, overcurrent protection, and overtemperature protection.

Target applications include telecommunications, test and measurement applications, and high-end consumer

products. This product is available in both through-hole and surface-mount package options, including tape and

reel.
