| | +-- Single digit variant (0-9)
| +-- 3-4 digit series (e.g., 808, 720, 628)
+-- SY or SYX (extended line)
Example Decoding
SY8088AAC
|| | |||
|| | ||+-- C = Part of QFN suffix
|| | |+-- A = Part of QFN suffix
|| | +-- A = Package code start

|+-- SY808 = DC-DC buck converter series
+-- Silergy prefix
SY7208QNC
|| | |||
|| | ||+-- C = Part of QFN suffix
|| | |+-- N = QFN variant
|| | +-- Q = Package start

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
