The circuit schematics , bill of materials (BOM), test measurements, and results are provided.
Complete 5 V single supply 8-channel multiplexed data acquisition system with integrated PGIA for industrial grade signals
The portable 3D scanning reference design uses Texas Instruments' DLP software development kit (SDK) , allowing developers to easily build by integrating TI's digital micromirror device (DMD) technology with cameras, sensors, motors or other peripherals Detailed 3D point cloud. Ideal as a compact or handheld solution, this high-resolution 3D scanner system utilizes the DLP® LightCrafter™ Evaluation Module (EVM) featuring the DLP3000 WVGA DMD to ensure flexible control of structured lighting solutions in industrial applications precise graphics.
This reference design is a tiny 3-W auxiliary power supply reference design driving four outputs – two of them isolated to power some drivers. The wide input range is 6 V to 60 V, so 1:10 - here a discrete LDO is needed to expand BIAS voltage for controller LM51551. For lowest EMI, a SEPIC topology is used to ensure low reflected ripple and to avoid RF ringing at the switch node. The control loop is closed on the primary side to save additional cost of optoisolator. Dual feedback allows any weighted feedback in between 3.3-V / 11-V outputs.

REF_ICL8810_LED_42W_PSR This 42 W reference design uses Infineon's high power factor flyback controller ICL8810. The evaluation board is a constant voltage (CV) secondary side regulation (SSR) system designed for use with a constant current (CC) converter for LED lighting applications.
This application note describes a backlight LCD application in which two adjacent CCFL lamps share a common, low-voltage side lamp connection. This design is found in automotive, industrial, and avionic applications. The article describes how a DS3882 CCFL controller can be used to drive the two CCFL lamps that share a common return.
The MAXREFDES1209 operates over a 14V to 60V input voltage range to deliver output voltage regulated at 12V and up to 500mA of load current.
The long strings of LEDs commonly found in TV and display backlighting, street lights, and parking garage lights require a current driver capable of producing high voltages. This reference design provides such a driver using the MAX16834, and demonstrates how very-high dimming ratios can be obtained.
The MAXREFDES1181 is centered around the MAX17501 ultra small, high-efficiency, high-voltage, synchronous stepdown DC-DC converter with integrated MOSFETs.
The MAX5073 is a dual converter capable of operating as a buck or boost converter. As a dual buck converter, this device can deliver up to 2A and 1A of output current. The reference design focuses on the MAX5073 operating as a buck converter with a switching frequency of 2MHz, which allows the use of smaller passive components and keeps it out of the AM band for automotive applications.
