EVLHV101SSR50W50 W converter using HVLED101 quasi resonant HPF flyback controller with secondary side regulation | DC/DC & AC/DC (Off-Line) SMPS Evaluation Boards | 1 | Active | The EVLHV101SSR50W is intended to provide a stable and insulated 60 V voltage for a maximum power of 50W.
It can be used as a standalone power supply or as a front end stage in a dimmable (or non-dimmable) off line LED driver.
A very high power factor, low THD and low BOM cost are obtained from this demonstration board thanks to the features of the HVLED101, which adopts frequency foldback with valley locking operation to reduce the switching losses and minimize acoustic noise.
Extremely low input power is obtained at no-load.
Input voltage variations, excessive input voltage (overvoltage like surges or bursts) and insufficient input voltage are managed by the HVLED101 protections, which improve the reliability of the application.
Output short-circuit and overload protection with auto restart behavior is implemented. |

| Evaluation Boards | 1 | Active | The EVLKSTCOMET10-1 is a development kit for the STCOMET platform, exploiting the performance capability of the full-feature STCOMET10 device. The STCOMET10 is a single device integrating a flexible power line communication (PLC) modem with a fully embedded analog front end (AFE) and a line driver, a high performance 3-channel metrology function and a Cortex®-M4 application core.
The kit is made of three modules: the STCOMET main board, the LCD module and the power supply board based on the VIPER26H.
With this development kit, it is possible to evaluate a complete single phase smart meter with PLC connectivity. The performance of the metering and application functions could be evaluated along with the PLC transmitting and receiving performance.
The PLC line coupling interface is designed to allow the STCOMET device to transmit and receive on the AC mains line using any narrow-band PLC modulation (single carrier or OFDM) up to 500 kHz, mainly for automatic meter reading (AMR) applications.
The default configuration of the PLC line coupling targets the G3-PLC (ITU G.9903) and PRIME (ITU G.9904) CENELEC A-band protocol standards. With a few BOM modifications, the STCOMET development kit can be adjusted to fit other narrow-band PLC protocols in CENELEC A-band or FCC band (e. g.: S-FSK IEC61334-5-1, IEEE 1901.2, G3-PLC FCC, METERS AND MORE).
If necessary, a specific customer's module can be designed and placed instead of the LCD module, for a different peripherals configuration.
As it can be seen from the EVLKSTCOMET10-1 picture, a special effort has been made to create the development kit compact and optimized to fit the size of a real meter.
The EVLKSTCOMET10-1 is suitable for the evaluation of the complete STCOMET platform. Featuring the full set STCOMET10 chip, the EVLKSTCOMET10-1 demonstrates at the same time all the functions and performance of the STCOM chips.
Please check for the EVLKSTCOMET10-1 hardware documentation, evaluation software and firmware libraries at st.com/powerline. For specific software or firmware releases, you may need to contact directly the STMicroelectronics sales office. |
EVLMG4-500WIBCKHigh power inverse buck for dimmable LED application with MASTERGAN4, HVLED002 and VIPER06XS | Evaluation Boards | 1 | Active | This document describes the EVLMG4-500WIBCK evaluation board, designed to drive a dimmable LED load with a GaN-based, synchronously rectified inverse buck topology; the switching element and diode are replaced by MASTERGAN4, mounted on a daughterboard to obtain a compact and scalable application. The HVLED002 controller manages the inverse buck mainly composed by T1 and MASTERGAN4.
The supply of the HVLED002 is generated by ViPer06XS, that converts the input voltage of the buck to the voltage needed at Vdd pin, eliminating the need of an external power supply.
The circuit is configured to generate 1 A, but different output currents are selectable changing the shunt resistor combination on the daughterboard with the MASTERGAN4.
The board operates with 400 V input voltage and output voltage range between 150 V and 350 V.
A dimming circuit is present on the board. It consists of two circuits: the analog and PWM circuit. It enables the regulation of the output current between the 100% and 0%.
The over voltage and short circuit protection are guaranteed. |
