The 60WLEDBULBGEVB Evaulation Board showcases an enhanced parallel-to-series LED lighting circuit. It uses updated control circuitry that allows the ability to accommodate multiple LED voltages by simply adjusting a single resistor (R3) as well as compensating for drift in LED voltage with temperature. It also has superb PF and THD performance, dimmability, low cost, and efficiency.
This circuit uses a parallel-to-series topology that dynamically adjusts LED load voltage as the instantaneous bridge output voltage varies. While a switch-mode power supply such as a buck converter reconfigures the input voltage to match the load, this circuit reconfigures the load to match the input voltage. When the instantaneous input voltage is relatively low, the LEDs are configured in parallel. When the instantaneously input voltage is relatively high, the LEDs are configured in series.
The circuit is designed for input voltages between 100 VAC and 140 VAC . ON Semiconductor CCRs are used to provide constant LED current and to protect LEDs from over-voltage conditions. The circuit employs an additional CCR (shown as CCR2) to increase LED current at high voltages for improved efficiency, PF, and THD performance.

The Dual Stepper Motor Driver Shield Evaluation Board evaluates the AMIS30543, a microstepping stepper motor driver for bipolar stepper motors. It has an on chip voltage regulator, reset output and watchdog reset able to supply peripheral devices. The chip is connected through IO pins and a SPI interface with an external microcontroller that is regulated through the PCA9655E's 16 bits of General Purpose parallel Input and Output (GPIO) expansion.
The AMIS-30543 is a micro-stepping stepper motor driver for bipolar stepper motors. The chip is connected through I/O pins and an SPI interface with an external microcontroller. It has an on chip voltage regulator, reset?output and watchdog reset, able to supply peripheral devices. AMIS-30543 contains a current?translation table and takes the next micro?step depending on the clock signal on the "NXT" input pin and the status of the "DIR" (=direction) register or input pin.
The chip provides a so-called "speed and load angle" output. This allows the creation of stall detection algorithms and control loops based on load-angle to adjust torque and speed. It is using a proprietary PWM algorithm for reliable current control. The chip is fully compatible with the automotive voltage requirements. The AMIS-30543 is ideally suited for general-purpose stepper motor applications in the automotive, industrial, medical, and marine environment. With the on-chip voltage regulator it further reduces the BOM for mechatronic stepper applications.

60W 16V SMPS Evaluation Board with F3 controller ICE3BS03LJG
Universal input power supply designed in a 16V 60W off line flyback converter that utilizes the F3 controller ICE3BS03LJG. The application board is operated in discontinuous current mode and running at 65 kHz switching frequency. It has one output voltage with secondary side control regulation. The ICE3BS03LJG is a current mode PWM controller. With the 500V startup cell, active burst mode and BiCMOS technologies, the standby power can be <100mW at no load. The frequency jitter mode and the soft gate drive can give a low EMI performance. The built-in 20ms blanking window and the extendable blanking time concept can prevent the IC from entering the auto restart mode due to over load protection unintentionally. The outstanding propagation delay compensation feature can allow a very precise current limit between low line and high line. For this IC, it provides both auto-restart and latch off protection mode. For those serious faults such as Vcc over-voltage, over temperature, short transformer winding, etc, the IC will enter the latched off protection mode. For the less severe case such as the over load, open loop, short opto-coupler, etc, it enter the auto restart protection mode. In case it needs customer defined protection, the external latch off enable feature can fulfill the requirement.
Возможности:
- 500V Startup Cell
- Active Burst Mode for lowest Standby Power
- Fast load jump response in Active Burst Mode
- 65kHz internally fixed switching frequency
- Frequency jitter and soft gate driving for low EMI

This reference design provides a flexible stepper motor system designed to drive up to two stepper motors, or 8 peripherals, while reducing the number of GPIOs needed from the host controller reducing overall cost. The system is suitable for applications requiring stepper motors or coils up to 50V, and a max current of 2.5A (with all channels enabled). This design features multiple configurations for outputs, allowing multiple peripherals to be driven (i.e. 1 motor, 1 buzzer, 1 relay, and 2 LEDs). It is adaptable to automated louver control in Heating Ventilation and Air Conditioning (HVAC) systems as well as control of relays, buzzers, and LEDs. This concept could also be more broadly expanded to drive any number of channels for other building automation designs including louver control in smart ventilation systems, automated window blind tilting, as well as pan and tilt control for IP cameras.
Возможности:
Subsystem Adaptable to a Wide Range of Building Automation Applications Only 3 GPIO Pins Required to Drive Any Multiple of 8 Channels Expandable to Desired Number of Drive Channels Adaptable across a wide range of drive applications - stepper motors, relays, LEDs High-Voltage (up to 50V), High-Current (up to 500mA per channel) drive outputs

Описание:
The UIC1WGEVB evaluation board showcases a simple, low cost, low part count chopper topology circuit. It is designed to safely operate with input voltages varying from 80 VAC to 280 VAC. ON Semiconductor CCRs are used to provide constant LED current and to protect LEDs from over-voltage conditions.
This circuit uses active switching to change how the load is being driven. The LED load will either be driven from the capacitor, C1, discharging, or directly from the AC source. The CCR ensures a constant current through the LED throughout all modes of operation. The switching point of the circuit may be changed by varying the resistor, R1. Changing this switching point will change the amount of time the capacitor is charging. If a higher power output is desired a higher current CCR can be used and the switching point will need to be changed. A metal oxide varistor and fuse are designed into the circuit for surge protection purposes.
