Power Integrations

The RDK-866 reference design describes a non-isolated buck converter power supply with an input-line zero-crossing detection output signal. The nominal output is 5 V/500 mA across the input range of 90 V to 300 V ac. 

The system is powered by the LinkSwitch-TNZ IC controller. The LinkSwitch-TNZ family of ICs combines power conversion with lossless generation of an ac zero-crossing signal used typically for system clock and timing functions. The device incorporates a 725 V power MOSFET, oscillator, a high-voltage switched current source for self-biasing, frequency jittering, fast (cycle-by-cycle) current limit, hysteretic thermal shutdown, and output and input overvoltage protection circuitry in a monolithic IC. 

Designs using the highly integrated LinkSwitch-TNZ ICs are more flexible than discrete implementations, reducing component count by 40% or more. The key design goal is low cost, low audible noise and compact form factor for use in wireless and relay power supplies.


The RGB LED lighting shield is compatible with Arduino as well as Infineon’s XMC1100 boot kit. It is easily configurable for various LED light engines and lamps, allowing for fast prototyping and cheap evaluation of LED lighting designs. 

The RGB LED lighting shield based on the XMC1302 microcontroller uses a dc-dc buck converter topology, and can drive up to three LED channels with a constant current. The shield’s XMC1302 MCU features an embedded brightness color control unit (BCCU) for flicker-free LED dimming and color control. 

The BCCU enables low-cost but high-quality LED lighting solutions, with minimal need for code generation. The RGB LED lighting shield also provides options for the evaluation of smooth, eye-friendly dimming and color mixing for various topologies

The EVL012LED is an LED driver board. The architecture is based on a two-stage approach: a front-end PFC pre-regulator and a downstream resonant half-bridge converter, using the new STNRG012 IC that integrates the controllers of both sections in a single device. 

The main features of this design are high efficiency, low power consumption at no load without an auxiliary supply, good power factor with low harmonic content, and reduced component count. 

The board also has a full set of protection features including output overload, short-circuit, and over-voltage, all of which can be easily defined as latched or auto-restart by changing a value in the non-volatile memory of the controller.


The STEVAL-ILD003V1 demonstration board implements a low-cost analog dimmer using the TS820-600FP, a sensitive-gate silicon-controlled rectifier (SCR) thyristor. The dimmer can drive typical low-power lamps such as compact fluorescent or dimmable LED lights.

Through-hole technology is used for the most important components, such as an LC filter, gate resistor, and turn-on delay capacitor, to allow for modification of the board.

The STEVAL-ILD003V1 eliminates flickering thanks to its continuous current applied through the sensitive SCR gate. This dimmer could easily replace a standard low-cost analog triac light dimmer using a diac-controlled circuit.
