The LM2674LDX-5.0/NOPB is a DC-DC switching regulator. It is a high-efficiency, monolithic, step-down switching regulator that is designed to provide up to 5.0A of system load current. It operates from an input supply voltage range of 4.5V to 45V, is logic controlled and is offered in IC form. The LM2674LDX-5.0/NOPB is ideal for high voltage power supplies that require very high efficiency and fast switching speeds. Moreover, the LM2674LDX-5.0/NOPB features a low noise, low profile power solution for critical low voltage applications.

The LM2674LDX-5.0/NOPB application fields are numerous and varied, ranging from external power supplies, telecom and car audio systems, to hand-held instrumentation, bar code scanners, and many more. This switching regulator is useful for any device which requires a direct current voltage that is different from the nominal the input voltage. The LM2674LDX-5.0/NOPB is particularly useful for applications that require low external component count and a wide input voltage range.

Like all DC-DC switching regulators, the LM2674LDX-5.0/NOPB works on the principle of converting a fixed DC input to a variable DC output. This switching regulator uses an inductor and a capacitor as components in its internal circuit. These two components are connected in series to convert a higher input voltage to a lower output voltage, a process known as buck conversion.

The LM2674LDX-5.0/NOPB relies on a bank of internal MOSFET transistors and diodes to create a bridge between the input and output stages. These components alternate between different levels, and by controlling the on-off cycle of the transistors, a higher input voltage is bucked down to the lower output voltage desired. This concept is known as Pulse Width Modulation (PWM).

At the heart of the LM2674LDX-5.0/NOPB is an advanced control loop that provides fast transient response, line and load regulation, and allows for a wide range of adjustment of output voltage. This on-chip control system also allows for easy and convenient user programming of output voltages. The LM2674LDX-5.0/NOPB also features a self-protecting overtemperature shut-down mode.

The LM2674LDX-5.0/NOPB is a high-quality, high-efficiency, low-profile DC-DC switching regulator. It is ideal for applications that require high-power efficiency and fast switching speed, allowing for a wide range of adjustment of output voltages. The LM2674LDX-5.0/NOPB features an internal control system that ensures fast transient response and line/load regulation. It is an ideal solution for engineers looking to power their systems with an efficient and reliable DC-DC switching regulator.
