Product Description Details
The LM2841XMKX-ADJL belongs to Texas Instruments' SIMPLE SWITCHER® product family, categorised as a PWM DC/DC buck regulator. This device is optimised to provide designers with an efficient, compact power management solution.
Input/Output Capabilities: The LM2841XMKX-ADJL supports a wide input voltage range of 4.5V to 42V, enabling adaptation to various unregulated power sources such as industrial power adapters and battery packs. Its output is adjustable with a feedback pin voltage of 0.765V, allowing flexible output voltage configuration via an external resistor divider.
Internal Design and Integration: The LM2841XMKX-ADJL incorporates an internal switch with low RDSON (typically 0.9Ω), a key design feature for achieving high conversion efficiency. Additionally, an integrated compensation network simplifies external circuit design, reducing the number of external components and overall solution footprint.
Package and Physical Characteristics: The LM2841XMKX-ADJL utilises an ultra-thin SOT-6L package (also known as TSOT-23-6), with a package thickness of approximately 870μm. This makes it highly suitable for space-constrained portable electronic devices.
Specifications
Electrical Characteristics: The LM2841XMKX-ADJL delivers a maximum output current of 300mA at a switching frequency of 550kHz (X option). This elevated switching frequency permits the use of smaller inductors and capacitors. Its quiescent operating current (Iq) is 1.35mA.
Voltage Range: Input voltage spans 4.5V to 42V, with an adjustable output voltage range of 0.765V to 34V, covering the power supply requirements of most low-voltage integrated circuits.
Protection Features: The LM2841XMKX-ADJL incorporates built-in short-circuit protection, safeguarding the device from damage during output short-circuits. It also incorporates thermal shutdown functionality, automatically deactivating when the chip temperature exceeds safe limits, providing multiple layers of safety assurance.
Environmental Adaptability: The LM2841XMKX-ADJL operates within a junction temperature (TJ) range of -40°C to +125°C. This wide temperature tolerance enables its use in demanding industrial and automotive applications.
Product Features
High Efficiency and Low Power Consumption: The LM2841XMKX-ADJL achieves typical efficiency of up to 85% through its low on-resistance internal switch. In shutdown mode, quiescent current is only 16μA, significantly reducing system standby power consumption and extending battery-powered device runtime.
Soft-Start Functionality: The device supports soft-start via the SHDN pin in conjunction with an external RC circuit. Users can adjust the start-up time according to specific applications, effectively suppressing inrush current during start-up and reducing electromagnetic interference.
Simplified Design Process: Texas Instruments provides WEBENCH® Power Designer support for the LM2841XMKX-ADJL. This online tool assists engineers in rapidly selecting peripheral components, performing performance simulations, and optimising designs, significantly shortening development cycles.
