Description : 16-BIT 40-KSPS LOW POWER SAMPLING ANALOG-TO-DIGITAL CONVERTER WITH INTERNAL REFERENCE AND PARALLEL/SERIAL INTERFACE
The ADS8507 is a complete low power, single 5-V supply, 16-bit sampling analog-to-digital (A/D)
converter. It contains a complete 16-bit capacitor-based, successive approximation register (SAR) A/D converter with sample and hold, clock, reference, and data interface. The converter can be
configured for a variety of input ranges including ±10 V, 4 V, and 5 V. For most input ranges, the input voltage can swing to 25 V or –25 V without damage to the converter.
Description : Step-Down Converter with Input Overvoltage Protection Reference Design
This reference design details a power management circuit which is capable to be operated at a supply voltage which is temporarily exceeding the maximum recommended supply voltage of the DCDC converter used.
The protection is achieved by disconnecting the supply voltage and disabling the converter during the overvoltage events. The implementation is based on a completely integrated step down converter circuit enabling a small total solution while still capable of handling up to 3 A at the output.

AKD4555-E is an evaluation board for the portable digital audio 16bit A/D and D/A converter, AK4555. The AKD4555-E can evaluate A/D converter and D/A converter separately in addition to loopback mode (A/D → D/A). The A/D section can be evaluated by interfacing with AKM’s DAC evaluation boards directly. The AKD4555-E has the interface with AKM’s ADC evaluation boards. Therefore, it’s easy to evaluate the D/A section. The AKD4555-E also has the digital audio interface and can achieve the interface with digital audio systems via opt-connector.
• Compatible with 2 types of interface
- Direct interface with AKM’s A/D & D/A converter evaluation boards
- DIT/DIR with optical input/output
Description : The One-Transistor Forward Converter
The one–transistor forward converter is the most elementary form of transformer–isolated buck converter. It is typically used in off–line applications in the 100–300 watt region. This application note illustrates the approach one would take to design a high DC input voltage, one–transistor forward converter.
Description : Triple Outputs AMOLED Display Power Supply / 3 x 3mm 16 pin QFN package
The TPS65632A is designed to drive AMOLED displays (Active Matrix Organic Light Emitting Diode)requiring three supply rails, VPOS, VNEG and AVDD. The device integrates a boost converter for VPOS, an inverting buck boost converter for VNEG and a boost converter for AVDD which are suitable for battery operated products.
The digital control pin (CTRL) allows programming the negative output voltage in digital steps. The TPS65632A uses a novel technology enabling excellent line and load regulation.
Description : hase Dimmable, Single Stage Boost Controller for LED Lighting
The TPS92561 device is a boost controller for LED lighting applications utilizing high-voltage, low-current LEDs. A boost converter approach to lighting applications allows the creation of the smallest volume converter possible and enables high efficiencies beyond 90%.
The device incorporates a current sense comparator with a fixed offset enabling a simple hysteretic control scheme free of the loop compensation issues typically associated with a boost converter. The integrated OVP and VCC regulator further simplify the design procedure and reduce external component count.
