The TPS82672EVM-646 is a high performance, low power Alternative Off-Line (AOL) Evaluation Module (EVM) that allows users to evaluate TI’s TPS82672A AOL regulator. This EVM is designed specifically for 75W and 100W applications up to 700 VA. It features a high efficiency (94%~95% @90VAC/12Vout) and a wide input voltage of 75VAC-265VAC.

The evaluation board is designed to be easily used for a range of applications that require DC/DC & AC/DC (Off-Line) SMPS solutions. It can be used in a variety of applications such as notebook computers, desktop PCs, servers, industrial/communications AC/DC adapters, and smart phones/tables. TPS82672EVM-646 can also be used in applications that require high efficiency and low standby power. In addition, it also provides overvoltage/overtemperature protection and power good indicator.

The main component of the TPS82672EVM-646 is the TPS82672A, an off-line switch mode power supply (SMPS) controller IC. This device is specifically designed to achieve 94%~95% efficiency at 90VAC/12V output. It has a wide operating input voltage range of 75VAC-265VAC as well as an adjustable output voltage of 5V-21V and an adjustable current of up to 6.5A.

TPS82672A employs TI\'s proprietary, high-speed, low-power control topology, which enables a full protection feature set, such as overvoltage, overcurrent, short circuit, and overtemperature protection. The device also provides an Expand PWM signal which can be used by the user to drive an external totem pole Transistor for increased current capability. In addition, the device supports continuous operation at full load with a power good signal output.

The TPS82672EVM-646 also integrates auxiliary components, such as Sense Resistor, MOSFET, Capacitors, Inductors, etc., to configure the power stage. The board provides four header pins that allow the user to control and obtain the system operations. The main output voltage can be adjusted through two sense resistors and programmed using the on-board potentiometer.

The TPS82672EVM-646 is an easy-to-use and comprehensive solution for evaluating TI’s TPS82672A, a high-performance, low-power alternative off-line (AOL) regulator. The board allows a wide input voltage of 75VAC-265VAC and an adjustable output voltage of 5V-21V. It employs TI\'s proprietary, high-speed, low-power control topology, which enables a full protection feature set, such as overvoltage, overcurrent, short circuit, and overtemperature protection.
