Microchip Technology, Inc. LED Drivers MSL2023-INR

The MSL2023-INR is a dual-string LED driver designed for applications requiring two-color or unequal forward voltage LEDs. It features individual PWM dimming with phase-shifted register control, allowing for precise control over brightness levels. The driver operates with a power supply range of 9.5V to 15V and utilizes a linear current controller for the main LED string, ensuring high accuracy and minimal ripple current. This product includes adaptive headroom control for various AC/DC or DC/DC topologies, enhancing efficiency across different configurations. It supports over 100:1 dimming range and incorporates an 8-bit DAC for peak current control, enabling fine adjustments to LED current. The MSL2023-INR is housed in a compact 24-pin QFN package and is rated for an operating temperature range of -40°C to +105°C, making it suitable for a variety of environmental conditions. Typical applications include general and architectural lighting, high CRI LED fixtures, downlights, and PAR lamps. The device also features open and short LED detection, an I²C interface for driver settings, and an open-drain fault indicator output, providing additional functionality for integration into lighting systems.
