Introduction

The LM5006MM/NOPB is a monolithic integrated circuit (IC) of voltage regulators or DC-DC switching regulator.This IC has been designed for applications requiring continuous output current of up to 5 A at a constant voltage of 5 V, making it an ideal choice for embedded solutions.The LM5006MM/NOPB has a boost type architecture, where the output voltage is much greater than the input voltage.It also provides excellent transient response over the full load range, with times of just a few microseconds.Moreover, it is one of the few switching regulators that does not require the use of an external sense resistor.

Application

The LM5006MM/NOPB can be used in a variety of applications, including fixed and adjustable applications requiring output currents of up to 5A. Possible applications are embedded systems, telecommunications systems, automotive electronics and communications gear.The LM5006MM/NOPB can also be used to power LED displays and low-voltage DC motors.Moreover, the LM5006MM/NOPB can be used in point-of-load (POL) DC-DC converters or power supplies. It is well-suited for distributed power systems (DPS), and can be used to provide supply voltages of up to 48V.

Working Principle

The workings of the LM5006MM/NOPB can be understood in terms of its intricate topology. Its operation as a switch-mode regulator can be broken down into three basic steps. A simplified diagram of the working principle is included below.1. First, an input voltage is supplied to an internal switch, and is then turned on and off at the switching frequency (fSW). This will cause an inductor to store energy.2. Second, when the switch is on, energy from the inductor will be delivered to the output indicating a positive current flow. When the switch is off, the energy will be returned to the input indicating a negative current flow. This process will repeat itself in a cycle, ensuring that the output voltage is kept at a constant level.3. Lastly, the internal error amplifier monitors the output voltage, and adjusts the duty cycle of the switch accordingly. This will ensure that the output voltage remains within the predetermined voltage regulation range.

Conclusion

The LM5006MM/NOPB is a monolithic integrated circuit (IC) of voltage regulators or DC-DC switching regulator.This IC has been designed for applications requiring continuous output current of up to 5 A at a constant voltage of 5 V, making it an ideal choice for embedded solutions. The LM5006MM/NOPB has a boost type architecture and can be used in a variety of applications, including fixed and adjustable applications requiring output currents of up to 5A. Its working principle can be broken down into three basic steps and involves switching the energy from an inductor to either the input or output voltage to provide a consistent output voltage. The LM5006MM/NOPB offers excellent integration, reliability, and low cost per watt, making it an excellent choice for embedded solutions.
