LM2614BTL

The LM2614BTL is a special purpose voltage regulator from Texas Instruments. It is a part of their Power Management Integrated Circuits (PMIC) product line, specifically designed for use in buck converters and adjustable power supplies. The LM2614BTL is a low-cost, low-power voltage regulator designed to provide the most efficient use of input voltage for powering small electronic devices.

The LM2614BTL provides an adjustable output voltage range of 0.90V to 5.5V with a maximum output current of 2A. The regulator works by actively controlling the current into a load with a narrow on-time pulse-width modulation (PWM) control signal, resulting in a much lower quiescent current than a traditional linear regulator. This makes it ideal for use in small, handheld devices.

The LM2614BTL features several protection features to ensure its safety and reliability, such as over-current protection and thermal shutdown. It also features programmable soft start, which allows the voltage regulator to slowly increase its output current to avoid excessive inrush current. The device also includes an adjustable current-limit setting, allowing it to protect itself and the load from short-circuits or overloads.

The LM2614BTL offers several external components that allow the user to customize the regulator’s performance. These components include resistor-capacitor (RC) networks and feedback resistors that determine the voltage regulation and output current. The LM2614BTL also allows the user to set the current limit with an external resistor.

Overall, the LM2614BTL is an ideal choice for adjustable power supplies and buck converters that require low power and cost. It offers low quiescent current, programmable soft start, adjustable current limit, and protection features, which make it a versatile and reliable device for powering small electronic devices.
