# Silergy Corp Manufacturer Skill ## MPN Structure Silergy MPNs follow this general structure: ``` [PREFIX][SERIES][VARIANT][PACKAGE] | | | | | | | +-- Package code (2-5 letters): AAC, QNC, DFN | | +-- 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 || +-- 8 = Variant within SY808 series |+-- SY808 = DC-DC buck converter series +-- Silergy prefix SY7208QNC || | ||| || | ||+-- C = Part of QFN suffix || | |+-- N = QFN variant || | +-- Q = Package start || +-- 8 = Variant within SY720 series |+-- SY720 = DC-DC boost converter series +-- Silergy prefix SYX196 ||| || ||| |+-- 6 = Variant ||| +-- 19 = Part of series number ||+-- X = Extended product line indicator |+-- SY = Silergy prefix +-- Extended line part ``` --- ## Package Codes ### QFN Packages | Code | Package | Notes | |------|---------|-------| | AAC | QFN | Common QFN variant | | QNC | QFN | QFN with N variant | | QFN | QFN | Standard designation | ### DFN Packages | Code | Package | Notes | |------|---------|-------| | DFN | DFN | Standard DFN | ### SOT Packages | Code | Package | Notes | |------|---------|-------| | SOT | SOT-23 | Standard SOT-23 | | TSOT | TSOT-23 | Thin SOT-23 | ### CSP Packages | Code | Package | Notes | |------|---------|-------| | WLCSP | WLCSP | Wafer-level chip scale | | CSP | CSP | Chip scale package | ### SOIC/SOP Packages | Code | Package | Notes | |------|---------|-------| | SOIC | SOIC-8 | 8-pin SOIC | | SOP | SOP-8 | 8-pin SOP | --- ## Product Lines ### SY808x - DC-DC Buck Converters (Low Voltage Input) | Series | Description | Input Voltage | |--------|-------------|---------------| | SY8088 | Synchronous buck | 2.5V-5.5V | | SY8089 | Synchronous buck | 2.5V-5.5V | ### SY809x - DC-DC Buck Converters | Series | Description | Features | |--------|-------------|----------| | SY8090 | Buck converter | Standard efficiency | | SY809x | Buck converters | Various output currents | ### SY811x - DC-DC Buck Converters | Series | Description | Features | |--------|-------------|----------| | SY8113 | Buck converter | High efficiency | | SY811x | Buck converters | Various packages | ### SY720x - DC-DC Boost Converters / LED Drivers | Series | Type | Notes | |--------|------|-------| | SY7200 | LED driver | White LED driver | | SY7201-SY7209 | Boost converters | Step-up converters | ### SY800x - LDO Regulators | Series | Description | Output Current | |--------|-------------|----------------| | SY8009 | LDO | Low current | | SY800x | LDO series | Various ratings | ### SY628x - LDO Regulators (High Current) | Series | Description | Output Current | |--------|-------------|----------------| | SY6288 | High current LDO | Higher current capability | | SY628x | LDO series | Load switch features | ### SY698x - Battery Chargers | Series | Description | Chemistry | |--------|-------------|-----------| | SY6981 | Li-ion charger | Single cell | | SY6982 | Li-ion charger | With power path | ### SYXxxx - Extended Product Line | Series | Description | Notes | |--------|-------------|-------| | SYX196 | Extended line | Various functions | | SYXxxx | Mixed products | Newer designs | --- ## Handler Implementation Notes ### Package Code Extraction ```java // 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}).*$"); ``` ### Series Extraction ```java // SYX series returns "SYX" // Standard SY[0-9]{4} returns first 5 chars (e.g., SY808, SY720) if (upperMpn.matches("^SYX[0-9]{3}.*")) { return "SYX"; } if (upperMpn.matches("^SY[0-9]{4}.*")) { return upperMpn.substring(0, 5); // SY808, SY720, SY628, etc. } ``` ### LED Driver Detection ```java // Only SY7200 is an LED driver in the SY720x series // SY7201-SY7209 are boost converters private boolean isLEDDriver(String mpn) { return mpn.matches("^SY7200[A-Z0-9]*$"); } ``` ### Product Category Determination ```java 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 ""; } ``` --- ## Related Files - Handler: `manufacturers/SilergyHandler.java` - Component types: `IC`, `VOLTAGE_REGULATOR`, `LED_DRIVER` - Test file: `handlers/SilergyHandlerTest.java` --- ## 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 <!-- Add new learnings above this line -->
