Recycling Process:

1. Consultation: If you have inventory electronic components that need to be disposed of, you can send the IC/module inventory you wish to sell via email.

2. On-site Recycling: Our company will dispatch professional staff to collect your inventory electronic components on-site and conduct preliminary testing and classification of the components.

3. Quotation: The company will provide a corresponding recycling price based on factors such as the type, quantity, and quality of the recycled components.

4. Settlement: Once an agreement is reached, the specific transaction method for delivery can be negotiated.

I. LED Driver Evaluation Boards: From Intelligent Control to Efficient Drive

LED lighting, particularly in high-power industrial and automotive applications, demands exceptional efficiency, dimming precision, and reliability from drivers. ON Semiconductor's evaluation board solutions cover the full spectrum of requirements, from simple constant-current to intelligent programmable designs.

1. Intelligent Evaluation Boards: NCL31000 and Strata Platform

For applications requiring advanced diagnostics and intelligent control, such as smart building lighting or automotive lamps, ON Semiconductor's NCL31000 intelligent LED driver evaluation board represents a flagship solution. Its core chip integrates a highly efficient buck LED driver alongside two innovative auxiliary DC-DC converters, enabling direct power supply to on-board microcontrollers and various sensors. Its most notable feature is support for high-bandwidth analogue and PWM dimming down to zero current, delivering exceptional dimming linearity with accuracy to 0.1%. This perfectly resolves the flickering issues inherent in traditional LED dimming at low brightness levels. The evaluation board is compatible with Arduino expansion board interfaces, greatly facilitating prototype development and functional verification.

2. High-Performance Buck Evaluation Board: NCL30160

For general and industrial lighting applications requiring compact, efficient drivers, the STR-NCL30160-1A-LED-GEVB evaluation board delivers an optimised solution. This board evaluates the NCL30160 chip, an integrated buck constant-current driver featuring a 50-mΩ power MOSFET. Its key advantage lies in eliminating the need for external loop compensation, thereby simplifying design. Utilising ON Semiconductor's Strata Developer Studio software platform, the evaluation board enables real-time monitoring of critical telemetry data including input/output voltage and current, LED status, and temperature. This facilitates intuitive and efficient performance evaluation and parameter tuning.

3. Simplified Linear Constant-Current Solution: NSI45020AT1G

For low-power LEDs or applications requiring a simple, cost-effective, and reliable constant-current source (such as indicator lights or advertising backlights), engineers can even rapidly assemble circuits using a single discrete component. For instance, ON Semiconductor's NSI45020AT1G essentially functions as a ‘constant-current diode’. This linear constant current regulator (CCR) operates across a wide voltage range (0-45V), initiates operation with just 0.5V dropout voltage, and requires no external components. While not a complex evaluation board itself, circuits centred around it are remarkably straightforward to implement, offering engineers the most economical and rapid path for evaluation and prototyping.

II. Linear Regulator (LDO) and Ideal Diode Controller Evaluation Board

1. Linear Regulator (LDO) Evaluation Solution

LDOs, renowned for their low noise and rapid transient response, are extensively employed to power noise-sensitive analogue circuits, RF modules, or as secondary system power supplies. ON Semiconductor offers an extensive LDO product portfolio. When selecting an LDO, engineers typically seek evaluation or demonstration boards integrating the chosen chip. Standard configurations for such boards include:

Core LDO chip: Pre-soldered onto an optimally laid-out PCB.

Configurable peripheral network: Select different input/output capacitors via pads or jumper caps to evaluate stability.

Test points: Facilitate measurement of input/output ripple, load transient response, and power dissipation.

Key value: Enables engineers to directly verify the LDO's voltage drop, thermal performance, and PSRR (Power Supply Rejection Ratio) metrics under specific loads, avoiding oscillation issues caused by improper PCB layout.

2. Ideal Diode Controller Evaluation Solution

Ideal diode controllers are essential in systems requiring prevention of current backflow, implementation of OR-ing redundant power supplies, or reduction of hot-swap losses. They simulate the unidirectional conduction characteristics of a diode by driving an external MOSFET, yet exhibit extremely low voltage drop (determined by the MOSFET's Rds(on)), thereby significantly enhancing efficiency and reducing thermal dissipation.

On Semiconductor's corresponding evaluation boards typically:

Integrate the controller with MOSFETs: Demonstrate how to drive and select external discrete MOSFETs.

Simulate fault conditions: Provide rapid short-circuit testing capability to verify reverse current blocking and surge protection functionality.

Deliver efficiency comparison data: Visually demonstrate significant improvements in temperature rise and power dissipation compared to traditional Schottky diodes at equivalent current levels.
