Handler Implementation Notes

Package Code Extraction

// Silergy package codes are 2-5 letters after the part number
// Pattern: SY[X]?[0-9]{3,4}[PACKAGE]
// Examples: SY8088AAC -> AAC -> QFN
//           SY6288DFN -> DFN -> DFN

Pattern packagePattern = Pattern.compile("^SY[X]?[0-9]{3,4}([A-Z]{2,5}).*$");

Series Extraction

// SYX series returns "SYX"
// Standard SY[0-9]{4} returns first 5 chars (e.g., SY808, SY720)
if (upperMpn.matches("^SYX[0-9]{3}.*")) {
    return "SYX";
}
if (upperMpn.matches("^SY[0-9]{4}.*")) {
    return upperMpn.substring(0, 5);  // SY808, SY720, SY628, etc.
}

LED Driver Detection

// Only SY7200 is an LED driver in the SY720x series
// SY7201-SY7209 are boost converters
private boolean isLEDDriver(String mpn) {
    return mpn.matches("^SY7200[A-Z0-9]*$");
}

Product Category Determination

public String getProductCategory(String mpn) {
    String upper = mpn.toUpperCase();

    // Buck converters
    if (upper.matches("^SY808[0-9].*") ||
        upper.matches("^SY809[0-9].*") ||
        upper.matches("^SY811[0-9].*")) {
        return "DC-DC Buck Converter";
    }
    // Boost converters (not SY7200)
    if (upper.matches("^SY720[1-9].*")) {
        return "DC-DC Boost Converter";
    }
    // LED driver
    if (upper.matches("^SY7200.*")) {
        return "LED Driver";
    }
    // LDOs
    if (upper.matches("^SY800[0-9].*") ||
        upper.matches("^SY628[0-9].*")) {
        return "LDO Regulator";
    }
    // Battery chargers
    if (upper.matches("^SY698[0-9].*")) {
        return "Battery Charger";
    }
    return "";
}

Learnings & Edge Cases

SY7200 vs SY720x: SY7200 is specifically an LED driver, while SY7201-SY7209 are boost converters
SYX extended line: SYX parts are newer designs with 3-digit numbers (e.g., SYX196)
Package code length varies: Silergy uses 2-5 letter package codes (AAC, QNC, DFN, WLCSP)
Series numbering: SY followed by 4 digits, where first 3 digits identify the product family
High current LDOs (SY628x): These often include load switch functionality
Battery chargers (SY698x): Include power path management for Li-ion/Li-polymer cells
No automotive prefix: Unlike Richtek, Silergy doesn't use a separate prefix for automotive parts
