The **AMLDW-6035-RZ** is a high-efficiency, DC-DC step-down (buck) LED driver manufactured by **Aimtec**. This component is specifically designed to provide a constant current output, which is essential for maintaining the longevity and brightness stability of high-power LEDs. --- ### ## Technical Specifications The following table summarizes the key electrical parameters for the AMLDW-6035-RZ: | Parameter | Specification | | :--- | :--- | | **Input Voltage Range** | 7V to 60V DC | | **Output Current** | 350mA (Constant) | | **Efficiency** | Up to 97% | | **Operating Temperature** | -40°C to +85°C | | **Dimming Support** | PWM and Analog | | **Package Type** | DIP14 (Dual In-line Package) | | **Protection Features** | Short Circuit, Over-temperature | --- ### ### Core Electronic Features 1. **Wide Input Voltage Range:** Supporting up to 60V makes it highly versatile for industrial applications, automotive systems (24V systems), and architectural lighting where long LED strings are used. 2. **Dual Dimming Control:** The driver features a multi-function control pin: * **PWM Dimming:** Allows for digital brightness control by pulsing the signal. * **Analog Dimming:** Adjusts brightness by varying the DC voltage level on the control pin. 3. **High Efficiency:** By utilizing switching regulator technology rather than linear regulation, it minimizes heat dissipation. This allows the part to operate without an external heatsink in most conditions. 4. **No External Components Required:** The "Z" series is often characterized as a "plug-and-play" module. It integrates the inductor and capacitors internally, significantly reducing the PCB footprint and design complexity. --- ### ### Typical Application Circuit While the module is self-contained, a basic implementation looks like this: ```mermaid graph LR A[DC Power 7-60V] --> B[VIN Pin] C[Ground] --> D[GND Pin] B --> E[AMLDW-6035-RZ] E --> F[LED +] E --> G[LED -] H[Microcontroller] -- PWM --> I[Remote ON/OFF Pin] ``` --- ### ### Pinout Configuration (DIP14) The device usually utilizes a standard 14-pin DIP footprint, though many pins are omitted for spacing: * **Pin 1 & 2:** GND (Input Ground) * **Pin 3:** Remote ON/OFF / Dimming Control * **Pin 7 & 8:** LED - (Output Connection) * **Pin 9 & 10:** LED + (Output Connection) * **Pin 13 & 14:** VIN (Positive Input)
