The LM2621MM is a highly efficient voltage step-up (boost) IC component manufactured by Texas Instruments. It is designed to increase the voltage from a low-power source, such as a battery or a single-cell solar panel, to a higher level. With a wide input voltage range of 1.8V to 14V, this component is suitable for a broad range of applications.
One of the key features of LM2621MM is its high efficiency, which enables it to deliver maximum power without excessive energy waste. It achieves this through its low-resistance internal MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) switch, minimizing power losses during switching. This results in reduced heat dissipation and longer battery life, making it ideal for energy-conscious designs.
The IC supports adjustable output voltages, allowing flexibility for various applications. The output voltage can be easily configured using external resistors, ensuring compatibility with different loads or devices. The LM2621MM can boost the voltage up to 14V, making it useful for driving LEDs, LCDs, or powering other electronic components.
Additionally, this IC incorporates a Pulse Width Modulation (PWM) control scheme, which provides smooth, regulated output voltage without significant ripple or noise. It maintains stable voltage output even under fluctuating input voltage conditions, ensuring reliable operation of connected devices.
The LM2621MM also includes built-in overcurrent protection, preventing potential damage to the IC and other connected components
