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.

TIEVM-HV-1PH-DCAC — Single phase inverter development kit with voltage source and grid connected modes

此参考设计使用 C2000 F28377D 微控制器来实施单相逆变器(直流-交流)控制。此设计支持逆变器的两种工作模式。第一种模式是采用输出 LC 滤波器的电压源模式,这种控制模式通常用于不间断电源。第二种模式是具有输出 LCL 滤波器的并网模式,这种模式通常用于太阳能逆变器。此设计的固件在 powerSUITE 框架下受支持,因此允许使用解决方案适配器进行适配,并可使用补偿设计器和 SFRA 来调节控制环路。高效、低 THD 和直观的软件使此设计对从事 UPS 的逆变器设计以及替代能源应用(例如,光伏逆变器、电网存储、微电网)的工程师很有吸引力。
