LM2623ALD/NOPB  

DC Switching Voltage Regulators

LM2623ALD/NOPB Description

The LM2623ALD/NOPB from Texas Instruments is a high-efficiency, adjustable boost DC-DC switching regulator designed for applications requiring step-up voltage conversion. This monolithic IC delivers up to 2.2A switch current with an input voltage range of 0.8V to 14V, making it ideal for low-voltage or battery-powered systems. The output voltage is adjustable from 1.24V to 14V, providing flexibility for diverse power requirements. Operating at a switching frequency range of 300kHz to 2MHz, it balances efficiency and component size, suitable for compact designs. Packaged in a 14-pin WSON (Wafer-Scale Small Outline No-Lead) form factor, it supports surface-mount assembly and complies with RoHS3 and REACH environmental standards.

LM2623ALD/NOPB Features

• Wide Input Range (0.8V–14V): Supports ultra-low-voltage sources, including single-cell batteries (e.g., NiMH, alkaline).
• High Output Current (2.2A Switch): Enables robust power delivery for demanding loads.
• Adjustable Output (1.24V–14V): Precision feedback control via external resistors.
• Programmable Frequency (300kHz–2MHz): Optimizes efficiency and reduces external component size.
• Non-Synchronous Topology: Simplifies design while maintaining high efficiency (up to 90%).
• Compact WSON Package: Saves board space in space-constrained applications.
• Robust Protection: Includes thermal shutdown and current limiting for reliability.

LM2623ALD/NOPB Applications

This regulator excels in scenarios requiring efficient step-up conversion:

• Battery-Powered Devices: Portable electronics, medical sensors, and energy harvesting systems.
• Industrial Systems: Powering microcontrollers, sensors, and actuators from low-voltage rails.
• Automotive Electronics: Auxiliary power supplies for infotainment or lighting systems.
• Consumer Electronics: USB power banks, LED drivers, and handheld instruments.
  Its ability to operate from sub-1V inputs makes it uniquely suited for energy-scarce environments, outperforming competitors with higher minimum voltage requirements.

Conclusion of LM2623ALD/NOPB

The LM2623ALD/NOPB stands out as a versatile, high-performance boost regulator, combining wide input range, high current capability, and compact packaging. Its programmable frequency and adjustable output cater to both efficiency-critical and space-sensitive designs. Whether in battery-operated gadgets or industrial systems, this IC delivers reliable power conversion with minimal external components, reducing BOM cost and complexity. For engineers seeking a balance of performance and integration, the LM2623ALD/NOPB is a compelling choice.
