The **YEV09T06-R** is a high-performance, non-isolated Point-of-Load (POL) DC-DC converter manufactured by Bel Fuse Inc. (formerly under the Power-One brand). It is part of the **Y-Series** family, designed to provide high-efficiency power regulation for distributed power architectures. --- ## 1. Technical Specifications Below are the primary electronic characteristics of the YEV09T06-R: | Parameter | Specification | | :--- | :--- | | **Input Voltage Range** | 4.5V to 13.8V DC | | **Output Voltage (Adjustable)** | 0.59V to 5.1V DC | | **Maximum Output Current** | 6 Amperes (6A) | | **Maximum Output Power** | 30.6 Watts | | **Efficiency** | Up to 93% at 3.3V out | | **Switching Frequency** | 500 kHz (fixed) | | **Package Style** | SIP (Single In-line Package) - Through Hole | --- ## 2. Key Features and Protection The internal circuitry of the YEV09T06-R is engineered for stability and safety in sensitive electronic systems. ### A. Control and Regulation * **Programmable Output:** The output voltage is set using a single external resistor connected between the `Trim` pin and `GND`. * **Remote On/Off:** Includes a dedicated pin for logic-level control to enable or disable the converter remotely. * **Remote Sense:** Compensates for voltage drops across PCB traces to ensure precise regulation at the load. ### B. Integrated Protections * **Over-Current Protection (OCP):** Features a "hiccup" mode that protects the device during short circuits. * **Over-Temperature Protection (OTP):** Automatically shuts down if internal temperatures exceed safe operating limits. * **Under-Voltage Lockout (UVLO):** Prevents the device from operating if the input voltage is too low to ensure stable output. --- ## 3. Pin Configuration The YEV09T06-R typically utilizes a 5-pin or 6-pin layout depending on the specific SIP orientation. | Pin Number | Name | Function | | :--- | :--- | :--- | | 1 | **Vin** | Positive Input Voltage | | 2 | **GND** | Power Ground | | 3 | **Vout** | Regulated Output Voltage | | 4 | **Trim** | Output Voltage Programming | | 5 | **ON/OFF** | Remote Control Input | | 6 | **Sense** | Remote Sense (Positive) | --- ## 4. Typical Applications Due to its high power density and efficiency, this part is commonly found in: * **Telecommunications:** Powering ASICs and FPGAs. * **Data Networking:** Servers, routers, and switches. * **Industrial Systems:** Distributed power bus architectures. ---
