MIFARE DESFire EV1 is an ISO14443A RFID transponder and an NFC Type 4A Tag Platform that is used in many NFC and RFID security applications due to the ability it has to operate in the clear or operate as a secure transponder using AES Encryption. This design uses the TI AES library along with a M

This reference design provides isolated positive and negative voltage rails required for Insulated Gate Bipolar Transistor (IGBT) gate drivers from a single 24-volt DC input supply. IGBTs are used in three phase inverters for variable-frequency drives to control the speed of AC motors. This reference design uses a push-pull isolated control topology and provides isolation compliant to IEC61800-5 and is intended to operate from a pre-regulated 24Vdc input.With a regulated (within 5%) input source: a simple open-loop: free-running oscillator can be implemented with a push-pull PWM controller. This topology is essentially a forward converter with two primary windings used to create a dual-drive winding. This fully utilizes the transformer core's magnetizing current more efficiently than flyback or the forward topologies. Another advantage this configuration has over flyback and forward configurations is that the supply output can be scaled up for higher power drives.This reference design also takes advantage of another benefit of the push pull topology in that multiple transformers can be controlled in parallel from a single controller to generate all the isolated voltage rails required for 3-phase IGBT inverters.Lastly: larger IGBTs for higher power drives sometimes require more gate drive current than what is provided by a typical IGBT gate driver: for which designers often use additional transistors for gate current boosting. This reference design provides +16V on the positive outputs and -8V on the negative outputs to compensate for the added voltage drop in those transistors.

The TIDA-01352 enables modular and efficient power scaling capability by providing a solution for digitally programmable power supply for powering ultrasound transmit circuit. The design uses push-pull topology to generate high-voltage (HV) and low- (LV) or MID- voltage power supplies. The HV rails are programmable from ±50V to ±150V: whereas the LV or MID rails are programmable from ±2.5V to ±50V. The power supply is capable of providing a continous power of 100-W on each rail. The programmability is implemented using onboard: 12-bit digital-to-analog converters (DACs). All the power supply rails are capable of being synchronized to a master clock. The design is scalable and modular allowing same supply to be duplicated or removed depending on number of channels and number of levels of pulser. The reference design also consists of other LV power supplies necessary for the pulser operation. This reference design is ideal for the high-voltgae DC-DC boost stage to use in conjuction with the floating (post) regulator design TIDA-01371.

PMP9490 is a 225W four Switch Buck –Boost Design utilizing best in Class Synchronous Buck Boost Converter LM5175.  The design accepts an input voltage of 9.5Vin to 20Vin and provides the outputs of 15V@15 (online only) A for Cons

TIDA-00200 proposes an interleaved flyback topology for battery charger applications that require an output power level of ~200 W with a minimized bill of material. Besides the actual electronic components: the efforts for cooling are a major contributor to the overall design cost. By taking advantage of the LM5032 high voltage dual interleaved current mode controller: the design accomplishes great efficiency of 90% at full load and spreads out the heat for reduced cooling efforts. A fan is typically not needed. The need for smaller form factor heat sinks provides additional design flexibility.
