What is the switching frequency?

The switching frequency is 3 MHz.

How do I enable or disable the module?

Connect the EN pin high to turn on the module and low to turn it off. Leaving it open turns it off due to an internal pull-down resistor.

AI-Powered supplier vetting

SummaryThe supplier is identified as a combined company associated with NATIONSTAR, a large LED manufacturing group founded in 1969, with stated large-scale facilities and workforce. It demonstrates broad customization, ODM, R&D, OEM, inventory, manufacturing coordination, and quality-process capabilities. Export activity is substantial, with stated self-operated import/export rights and 90% of sales from exports. Lead times are stated as within 15 working days in both peak and off-season periods. However, the supplier has no overseas warehouse, showroom, agents, or branches, and the evidence does not establish certifications, specific after-sales service performance, or customer case details. Financial information is insufficient for a credibility assessment and is not reported here.

Supplier typeThe supplier is classified as a combined company, while its company description identifies the mother company as NATIONSTAR, a national-level key high-tech enterprise engaged in LED components and LED application products. This supports identification as a manufacturing-oriented supplier rather than a purely trading entity.

After-Sales capabilityThe supplier has documented procedures and records for handling customer complaints and corrective/preventive actions, indicating structured service-response processes. However, it has no overseas warehouse, showroom, agents, or branches, and no direct evidence quantifies after-sales coverage or outcomes.

R&D capabilityThe supplier reports new products during the past year, provides ODM services, and has R&D capability; its parent is described as a long-established high-tech LED manufacturer. The absence of an available SDK limits evidence of software or platform integration capability but does not negate the stated product R&D capability.

Production capacityProduction capability is supported by listed die bonding, wire bonding, AOI, and taping equipment, valid contracts with associated subcontractors, inventory capacity, documented inspection procedures, and stated lead times within 15 working days. The parent company is also described as a large-scale LED manufacturing operation with more than 6,000 employees.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. It also reports ODM availability, providing direct evidence of broad customization capability.
