(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 EPC9102 demonstration board is a 12 V output, 375 kHz phase shifted full bridge (PSFB) eighth brick converter with 17 A maximum output current and 36 V to 60 V input voltage range. The demonstration board features the EPC2001 enhancement mode (eGaN®) field effect transistors (FETs), as well as the first eGaN FET specific integrated circuit driver – the National LM5113 from Texas Instruments. …

Demonstration circuit DC1198A-A features the LTM®4605EV, the high efficiency, high density switch mode buck-boost μModule® regulator. The LTM4605EV can regulate its output voltage from an input voltage above, below, or equal to the output. The input voltage range of DC1198A-A is from 4.5V to 20V with a preset output voltage of 12V. The rated load current is 5A, although derating is necessary for …

Demonstration circuit DC1194A features the LTM®8020, a 200mA DC/DC step-down μModule® regulator. The board is preset to deliver a 3.3V output at up to 200mA load current from an input voltage of up to 36V. The output voltage may be modified by simply changing one resistor.

Demonstration circuit DC1041A-A features the LTM®4601EV, a 12A high efficiency, high density switch mode step-down converter. The input voltage range is from 4.5V to 28V. The output voltage is jumper selectable for popular voltages from 0.6V to 5V. The PLLIN pin supports synchronizing the μModule® regulator to an external clock.

Demonstration circuit DC1084A-B features the LTM®4602HV, the high efficiency, high density step-down μModule® regulator. The input voltage range is from 4.5V to 28V. The output voltage is jumper programmable from 0.6V to 5V, refer to the step-down ratio curve in the LTM4602HV data sheet.

The MAX13256 evaluation kit (EV kit) is a fully assembled and tested PCB that contains the MAX13256 10W isolated H-bridge DC-DC converter. The EV kit operates from an 8V to 36V DC power source and the on-board 1:1 turns-ratio transformer from HALO sets the output voltage range from 6.8V to 34.8V with a 300mA current limit.
