I2C to dual PWM controller. The LED-Warrior18, manufactured by Code Mercenaries, is an I2C to dual channel PWM LED driver specifically designed to provide seamless brightness control for LED applications. This component, available in SOIC8 package (LW18-S) and as a ready-to-use module (LW18-01MOD), offers dual 16-bit PWM outputs with a dimming range from 0.001% to 100% and operates at a PWM frequency of 730 Hz. It supports programmable period lengths for higher-frequency or lower-resolution operation and includes an 8-bit data to logarithmic mapping feature for smoother dimming operations with just 256 steps. The LED-Warrior18 is engineered for minimal external circuitry with a 5V power supply requirement, offering ease of use in various lighting applications. It also features a sync mode for synchronized control of multiple units and customizable power-on status settings, making it highly versatile for standalone operations or integrated systems. Additionally, custom variants of both the chip and module are available, catering to specific application needs. The module version, LW18-01MOD, simplifies integration by including terminal blocks and supporting up to 4A load sink current for each output. The LED-Warrior18 stands out for its straightforward interface and operational flexibility, providing a comprehensive solution for advanced LED dimming and control projects.

The LED-Warrior10, developed by Code Mercenaries, is a versatile PWM (Pulse Width Modulation) Dimmer Controller designed for LED applications, delivering features such as flicker-free operation at 730 Hz, logarithmic dimming, and minimal external circuitry requirements. Available in DIL8, SOIC8 packages, and also as a ready-to-use module (LW10-01MOD), this component caters to a wide range of lighting solutions by supporting both potentiometer and button-based dimming inputs. It allows for dual-button as well as single-button dimming modes, providing flexibility in user interface design. The LED-Warrior10 stands out with its capability to store programmable power-on and minimum values, ensuring a customized lighting experience. It operates on a 5V supply for the chip itself, while the module version supports a broader range of 5.5V to 40V, capable of delivering a maximum PWM output of 4A for driving LED assemblies directly. Designed with the end-user in mind, the LED-Warrior10 also features settings for adjusting the power-on value and minimum dimming level to accommodate various LED setups, particularly beneficial for scenarios involving replacement LED lamps. The component is ideal for designers and engineers looking for a reliable, high-performance solution for their LED dimming control applications.
