The bundle of a TI SN6501 Transformer Driver together with Wurth Electronics WE-PP Push-Pull transformers is one of the industries smallest, simplest, and most cost-effective solutions for isolated interface designs. This bundle is perfect to use for CAN or RS485 designs as well as other interface designs with the need of isolation or isolated DC/DC converter designs.
Texas Instruments SN6501 Transformer Driver is a monolithic oscillator/power-driver designed for small form factor, isolated power supplies in isolated interface applications. TI SN6501 drives a low-profile, center-tapped transformer primary from a 3.3V or 5V DC power supply. The secondary can be wound to provide any isolated voltage based on transformer turns ratio. SN6501 Transformer Driver consists of an oscillator followed by a gate drive circuit that provides the complementary output signals to drive the ground referenced N-channel power switches. The internal logic ensures break-before-make action between the two switches. This TI device is specified for operation at temperatures from -40°C to 125°C.
Wurth Electronics WE-PP Miniature Push-Pull Transformers for SN6501 feature small size and high performance as well as a high isolation voltage of 2.5kV. These Wurth Push-Pull transformers are designed to provide designers with the most size- and cost-effective solution. SN6501 transformer driver is a push-pull driver for small transformers used in a variety of applications, such as isolated interfaces such as RS-485, RS-232, RS-422, I2C, or low power LAN.
TI TPS54160 60V 1.5A Step-Down DC/DC Converter with integrated Eco-mode™ and wide switching frequency range of 100kHz to 2.5MHz is perfect for the use in 12V/24V/48V industrial and commercial low power systems. To reach the highest possible efficiency value, use the Wurth Electronics WE-DD coupled inductors and WE-TPC power inductors with small sizes and low DCRs.
Texas Instruments TPS54160 step down Swift™ DC/DC converters provide input transient voltage protection that allows the device and the rest of a board to survive potentially damaging voltage spikes. These TI DC/DC converters retain low output voltage even with a 60V transient voltage pulse. The high-performance TI TPS54160 DC/DC converter family also provides light load efficiency, low quiescent current (ideal for applications based on TI MSP430 MCUs), a high switching frequency, and a small package size for space-limited designs.
Wurth Electronics WE-DD Coupled Inductors are available in two general package sizes: 7mm x 7mm and 12mm x 12mm. Different heights are available within these package sizes, allowing designers to select the product with the best mechanical and electrical characteristics for an application. Wurth Electronics has divided the WE-DD Coupled Inductors into two groups: One is designed for SEPIC and CUK applications and the other for typical non-isolated flyback topologies.
The Step-Down Converter family with Eco-mode™ from TI and WE-HCI Flatwire High Current Inductor build a team which is hard to beat. The operating temperatures of up to 150°C, ultra low DCR values of the flatwire inductors and low dropout at Light Loads of the IC makes this bundle a super efficient solution for 12V/24V/48V Industrial Power Supplies and Communication Power Systems.
Texas Instruments TPS54340 and TPS54540 are 42V input 3.5A and 5A step-down DC-DC converters with an integrated high side MOSFET. TI TPS54360 and TPS54560 are 60V input 3.5A and 5A DC-DC converters with integrated high side MOSFET. TPS54341 / TPS54541 and TPS54361 / TPS54561 devices offer 100kHz to 2.5MHz adjustable switching frequency while TPS543x0 and TPS545x0 devices have 100kHz to 2.5MHz fixed switching frequency. These TI step-down converters survive load dump pulses up to 65V per ISO 7637. All of the parts offer high efficiency at light loads with pulse skipping Eco-mode.
Wurth Electronics WE-HCI 1890 High Current Power Inductors feature high current capability with saturation current ratings up to 65A and low core losses at high frequency. Wurth Electronics magnetically shielded high current inductor WE-HCI 1980 series comes in an 18mm x 18mm x 9mm package size. Wurth Electronics WE-HCI 1890 High Current Power Inductors offer very low DCR tolerances due to the flat wire technology and a broad range of available inductance values (0.82µH up to 47µH), and an operating temperature of -40 °C to +125°C / +150°C.
TI bq25570 Ultra Low Power Management IC finds its usage in many different applications like Ultra Low Power DC/DC Boost Charger, Energy Storage, Battery Charging and Protection and Battery Good Output and many more. High Efficiency of up to 93% can be reached and continuous energy harvesting is possible from Vin as low as 100mV. Designing successfully such circuits requires the use of inductors with ultra low DCRs and tiny size. TI suggests the use of the new WE-MAPI Miniature Metal Alloy Inductors family with a footprint size of 2.5x2.0mm or 3.0x3.0mm.
TI bq25570 Ultra Low Power Harvester Power Management IC is a highly integrated energy harvesting Nano-Power management solution that is well suited for meeting the special needs of ultra low power applications. The product is specifically designed to efficiently acquire and manage the microwatts (μW) to milliwatts (mW) of power generated from a variety of DC sources like photovoltaic (solar) or thermal electric generators. The bq25570 is the first device of its kind to implement a highly efficient boost converter/charger with a nano-powered buck converter targeted toward products and systems, such as wireless sensor networks (WSN) which have stringent power and operational demands.
