The Indoor Light Energy Harvesting Reference Design for Bluetooth Low Energy (BLE) Beacon Subsystem provides a solution where by with just the power of the typical indoor lighting in a retail environment (greater than 250 LUX) the Bluetooth Low Energy chip can broadcast BLE beacons.This subsystem reference design is highly differentiated over existing solutions as it incorporates no batteries: thus eliminating the hassle of battery replacement: battery charging: and saving costs associated with battery maintenance. This solution also ensures that there are no constraints around installation as long as there is typical indoor lighting available. There is also no ON/OFF switch; the entire load connection and disconnection is handled by the power management IC therefore ensuring that the solution is self managing.

PMP7763 is a high voltage isolated DC/DC flyback converter. The input range is 30 – 800V and output is 24V @ 250mA. It has a high voltage hold off circuit. The secondary is open loop with no feedback control for the output. However: there is feedback control for the primary.

The CC2500EM reference design contains schematics and layout files for the CC2500EM evaluation module used in the CC2500-CC2550DK development kit. The reference design demonstrates good techniques for CC2500 decoupling and RF layout. For optimum RF performance: these parts should be copied accurately. This is a 2-layer reference design with a discrete balun and SMA antenna connector designed for a single ended 50 ohm antenna.

ADS4246 Evaluation Module

HVHB LEDs: when driven in a PFC boost configuration: have the advantages of small size: high PFC: high efficiency: low cost: and low complexity. This reference design is triac dimmable: taking universal AC in and drives 3 High Voltage LEDs at 10W.

This TI Verified Design is a -40dB band-pass filtered inverting attenuator. The circuit creates a filtered: inverted: and attenuated output from a single-ended input signal that can be used for test and measurement: or other waveform generation applications. A single low-noise OPA1611 op amp is used to invert: attenuate: and filter the input signal. The low-noise and low-distortion performance of the OPA1611 allows for a very accurate and clean output signals.See more TI Precision Designs

A transition mode (TM) Boost PFC and a TM Buck deliver from high line a clean 80mA current to a LED string: max. voltage 312V. The PCB board has been developed to fit into a T8 fluorescent tube: suitable for retrofit purpose. A PWM dimming input is also included.

Cost Effective PWM Buck Controller with 3.3V/3A output

Insulated Gate Bipolar Transistors (IGBTs) are used in high current three-phase AC motors. This application report discusses the theory and requirements of gate-drive power supply for IGBTs. It also discusses the isolation requirements and calculation of correct amount of IGBT drive power.

This wide input voltage range SEPIC operates from an input of 6V - 48V and produces greater than 89% efficiency. Its compact size and low cost make it idea for automotive and telecom applications.

PMP3060 uses 3 x TPS40180 in a three phase synchronous buck converter to generate 1.8V at 60A from a 12V input. The design operates at 250KHz per phase to keep the efficiency high. The 1.8V at 60A can be used for a number of applications including memory power supplies.

This application report presents an efficient and precise method on how to achieve the desired resonant frequency of configuring the trim array with only a few iterations and measuring the resonant frequency. First the minimum and maximum resonant frequency is measured; from this data a capacitance gradient is derived which allows a good prediction of the required capacitance. The calculated cap
