Starrystone Tech Products

Starrystone Tech offers four main product categories: AC-DC Controllers including PWM controllers and synchronous rectifiers for power supplies; DC-DC Converters including buck, boost, and buck-boost converters for voltage conversion; LED Drivers for general lighting and display applications; and Gate Drivers for controlling power MOSFETs and IGBTs. Each category includes multiple product series targeting different application requirements and performance levels.

Browse our product categories to find the right solution for your application. Contact our FAE team for selection guidance.

Selecting the right Starrystone Tech product involves several steps. First, identify your application requirements including input voltage range, output voltage/current, and power level. Second, determine the converter topology needed (flyback, buck, boost, etc.). Third, consider efficiency requirements and protection features needed. Fourth, evaluate package options and thermal requirements. Fifth, check for specific features like synchronous rectification or dimming control. Starrystone Tech provides selection guides and our FAE team can provide personalized recommendations.

Starrystone Tech's AC-DC controller series differ in power level, topology support, and features. Some series focus on low-power applications (under 30W) with high integration and minimal external components. Others target medium to high power (up to 100W+) with advanced features like active PFC and synchronous rectification. The STR-A series offers cost-effective solutions for standard adapters, while STR-B series provides higher performance with advanced protection features. Understanding these differences helps select the optimal solution for your specific power supply design.

Starrystone Tech offers several product series specifically designed for LED lighting applications. The STR-L series LED drivers provide constant current output with various current levels for different LED configurations. These drivers support analog and PWM dimming, making them suitable for both general lighting and smart lighting applications. For high-power LED applications, the STR-H series offers higher current capability and better thermal performance. The products support various topologies including buck, boost, and buck-boost for different LED string configurations.

For LED lighting designs, consider the STR-L series for standard applications or STR-H series for high-power requirements. Request reference designs from our team.

Starrystone Tech provides DC-DC converters supporting multiple topologies. Buck (step-down) converters are available for applications where input voltage is higher than output. Boost (step-up) converters suit applications requiring higher output voltage. Buck-boost converters handle both step-up and step-down operation, ideal for battery-powered applications where input voltage varies. The product portfolio covers various current and voltage ranges to meet diverse application requirements.
