Texas Instruments LM5175EVM-HD Evaluation Module
Texas Instruments LM5175EVM-HD Evaluation Module offers a 4-switch synchronous buck-boost DC/DC regulator that implements synchronous rectification. This feature allows exceptionally high conversion efficiency in a small footprint at 72W output power. The device operates over a 5.5V to 42V wide input voltage range with an adjustable output voltage from the nominal 12V utilizing only a single resistor or voltage source. This option enables the user to customize the output voltage from 0.8V to 24V as required.
The TI LM5175EVM-HD is ideal for applications where the input voltage varies continuously above, equal to, or below the regulated output voltage setpoint in buck, buck-boost, and boost operating modes, respectively.
