TLD5191IVREG_EVAL

Overview

TLD5191IVREG_EVAL - Evaluation platform for TLD5191ES synchronous MOSFET H-Bridge DC-DC controller.

The TLD5191IVREG-EVAL is an evaluation platform for the TLD5191ES, which can work as buck-boost LED driver, or as a voltage regulator.
The default configuration is constant current LED driver with 1.5 A maximum output current. The output current can be increased up to 6A or more by changing a shunt resistor.
