There are three switches on the evaluation board. SW1 and SW2 provide the designer with the flexibility of evaluating the performance of the UCC3918 when residing on either the system backplane or on an adapter card. Closing SW1 after SW2 simulates an application where the UCC3918 resides on a plug-in adapter card. Closing SW1 prior to SW2 simulates an application where the UCC3918 resides on the system backplane. SW3 provides a shutdown input to disable the IC.

The LM5575 and LM25575 switching regulators feature all of the functions necessary to implement an efficient high voltage buck regulator using a minimum of external components. These easy to use regulators include either a 42V (LM25575) or a 75V (LM5575) N-Channel buck switch with an output current capability of 1.5 Amps. The operating frequency is programmable from 50kHz up to 1MHz.
The SN74AVC2T244 is a 2-bit voltage level translator. This translator is a single direction voltage translator, with OE. When the output-enable (OE) input is high, all outputs are placed in the high-impedance state. The A port is designed to track VCCA. VCCA accepts any supply voltage from 0.9V to 3.6 V. The B port is designed to track VCCB. VCCB accepts any supply voltage from 0.9 V to 3.6 V.
The ADS5287EVM provides a platform for evaluating the eight-channel ADS5287 analog-to-digital converter (ADC) under various signal, reference, and supply conditions. The EVM provides an external SMA connector for eight analog inputs to the ADC and the input of the ADC clock. The ADC can be clocked using either a single-ended or differential clock, and provisions are made on the EVM to allow users to evaluate the ADC using a single-ended PECL clock, or a differential transformer-coupled clock.
The demo board included in this shipment uses the LM2735X 1.6MHz DC-DC switching regulator that converts 3V to 5.5V input to 12V output for up to 500mA load current depending on Vin. This is a 2-layer board using the bottom layer as a Ground plane.
The bq24060EVM is an evaluation tool for the bq24060 linear single-cell Li-Ion charger with thermal regulation and input over-voltage protection. The EVM is a complete designed-and-tested charger circuit that allows the user to test all functions of the bq24060 and to charge a single-cell Li-Ion battery with up to 1 A of continuous charge current. The EVM comes with a pre-programmed charge current setting of 0.7 A.
The TLV803SEVM-019 is a fully assembled and tested circuit that allows easy evaluation of TLV803S supply voltage supervisor (SVS) at a supply voltage of 3.3 V. TLV803S is an active low reset SVS. The output (reset) of the EVM will either be high (equivalent to supply voltage) when VDD is greater than the threshold voltage and low (0-V) when VDD is less than the threshold voltage.
THS4631EVM's is an evaluation Module for the DGN (8-pin MSOP power pad) package. The THS4631EVM's are designed to demonstrate the functionality and versatility of the device. The EVM is ready for power, signal source, and test instruments.
The TPS2560EVM-424 and TPS2561EVM-424 are evaluation modules (EVM) for Texas Instruments power-distribution switches with adjustable current-limit. These EVMs operate over a 2.5-V to 6.5-V range. An on-board jumper sets the output current-limit to either 0.5 A or 1 A. The board is designed for the 5-A capability of the TPS2560 or TPS25561.
The TPS54550EVM-158 evaluation module allows the designer to evaluate the TPS54550 SWIFT synchronous step down DC/DC converter optimized for small size. The inductor and capacitors selected allow a 6-17 V input and a 3.3 V output while supporting up to 5 A output. The output voltage can be easily adjusted by changing a resistor divider. This particular design switches at 700 kHz.
The ADS6424 EVM is a circuit board that allows designers to evaluate the performance of Texas Instruments‘ ADS6424 device, a quad channel 12-bit 105 MSPS analog to digital converter. The ADC features a configurable serialized LVDS outputs which can be directly deserialized using TI‘s companion TSW1400EVM or TSW1405EVM High Speed LVDS Deserializer System. The EVM provides a flexible environment to test the ADS6424 under a variety of clock, input and supply conditions.
