The converter's output voltage adjusts as needed to maintain a constant current through the LED array.

The EVM provides a convenient method for evaluating the performance of a charge management and system power solution for portable applications using the bq24072/3/4/5/9(T) and bq24230/2 product families. A completely designed and tested module is presented. The charger is designed to deliver up to 1.5 A of continuous current to the system or charger for one-cell Li-ion or Li-polymer applications (see the data sheet for correct device) using a dc power supply. The charger is programmed from the factory to deliver 0.9 A of charging current. This EVM was designed as a stand-alone evaluation module, but it also can be interfaced with the system and host via the connectors and headers.

The TPS5430EVM-342 evaluation module features the TPS5430 converter IC in a 2.25 A, inverting buck-boost design. The TPS5430 dc/dc converter is designed to provide up to a 3.0 A output from an input voltage source of 5.5 V to 36 V. Table 1 of the User Guide provides the rated input voltage and output current range for the evaluation module. This EVM is designed to demonstrate using the TPS5430 regulator in an inverting buck-boost application and does not reflect the entire design range of input and output voltages that can be used with this part. The switching frequency is internally set at a nominal 500 k Hz. The high-side MOSFET is incorporated inside the TPS5430 package along with the gate drive circuitry. The low drain-to-source on resistance of the MOSFET helps the TPS5430 to achieve high efficiencies and keep the junction temperature low at high output currents. The compensation components are internal to the integrated circuit (IC), whereas an external divider permits an adjustable output voltage. Additionally, the TPS5430 provides an enable input. The absolute maximum input voltage is 24 V.
