(From User Guide) The purpose of this document is to provide information on the STEVAL-ISA081V1 switched mode power supply (SMPS) demonstration board. The STEVAL-ISA081V1 is an isolated SMPS capable of delivering a 12 W output over a wide input voltage range. It is designed for a mains application focused on providing a cost-effective and space-saving solution.

The STEVAL-ISA044V6 demonstration board is based on the ST1S10 device assembled in a DFN package. The ST1S10 is a step-down DC-DC converter with the inhibit function optimized for powering high voltages in LCD applications and low voltages in digital-core HDD applications.

The TPS54327 is a single, adaptive on-time, D-CAP2™-mode, synchronous buck converter requiring a very low external component count. The D-CAP2™ control circuit is optimized for low-ESR output capacitors such as POSCAP, SP-CAP, or ceramic types and features fast transient response with no external compensation. The switching frequency is internally set at a nominal 700 kHz.

The TPS6208x synchronous switched mode converters are based on DCS™ Control (Direct Control with Seamless transition into Power Save Mode). This is an advanced regulation topology that combines the advantages of hysteretic and voltage mode control.

The Texas Instruments TPS62020 evaluation module (EVM) for low-power, high-efficiency, step-down converters helps designers evaluate this device. The EVM enables evaluation of different device modes and device performance.

The TPS64202EVM-023 is an evaluation tool for the TPS64202 inductive step-down controller in SOT-23 package which can supply voltages down to 1.2V from a 1.8-V to 6.5-V input.

The TPS40200EVM-001 evaluation module (EVM) uses the TPS40200 nonsynchronous buck converter to provide a resistor-selected 3.3-V output voltage that delivers up to 2.5 A from a 12-V input bus. The EVM operates from a single supply and uses a single P-channel power FET and Schottky diode to produce a low-cost buck converter. The part operates at a 300-kHz clock frequency with provision for externa…

The Texas Instruments TPS62050 and TPS62052 evaluation modules (EVM) for low-power, high-efficiency, step-down converters help designers evaluate these devices. The EVMs make it possible to evaluate different modes of the devices as well as the device performance.

The controller utilizes a constant on-time control scheme which eliminates the need for external compensation components, allowing the power supply designer to minimize necessary board space and reduce costs.

The TPS40090EVM−001 multi-phase dc-to-dc converter utilizes the TPS40090 multi-phase controller and UCC27222 predictive gate driver to step down a 12-V input to 1.5V @ 100 A at 420 kHz.
