The LM26001MXAX/NOPB is a DC-DC switching regulator. It is employed in applications with a wide input voltage range and is capable of providing a regulated and fast transient output voltage. From wearables to automotive, the device provides high performance and features. This guide explores the LM26001MXAX/NOPB application field and working principle.

Application Field

The LM26001MXAX/NOPB is optimized for operations in wide voltage applications, such as those found in industrial, aerospace and automotive. Due to its design, it provides high efficiency and fast transient response. This makes it suitable for applications in wearables and other battery-powered, demanding systems. Additionally, the device can be used as both a Step-down (Buck) and Step-up (Boost) regulator.

Features

The LM26001MXAX/NOPB DC-DC switching regulator is designed to address the power needs of a wide variety of applications. Here are some of its features:

• 2.7V to 27V input voltage
• Integrated PMOS with pre bias OVP. It enables operation in low-input-voltage environments
• Adjustable frequency up to 1MHz
• 0.6V feedback reference
• Built in over-temperature protection
• Stable with ceramic output capacitors
• Syncless operation mode. It enables the reduction of output ripple
• ±0.5% reference voltage accuracy

Packaging

The LM26001MXAX/NOPB is available in SO-8, SC70-5 and TDFN packages. Its body is exposed thermal pad and offers a package power dissipation of up to 2.7W. This makes it suitable for applications with compact requirements.

Working Principle

The LM26001MXAX/NOPB adopts a synchronous buck topology. It can deliver up to a maximum of 1.5A peak current. Its integrated PMOS is used for switching and is controlled by the peak current loop. A resistor operating in series with the PMOS creates the Peak Current Set Threshold (PCST) that sets the amount of current delivered to the load. The current is regulated by using a signal sampled from two resistors connected in series between the DRAIN pin and GND.

The LM26001MXAX/NOPB voltage regulator also has an Internal Soft Start (ISS), which set up the output of the regulator at a slow rate before reaching the desired voltage. This avoids unexpected voltage spikes that could damage components.

One of the most important features of the LM26001MXAX/NOPB is its switching frequency. By setting the COMP Voltage Threshold (VCOMP) to the desired value, the oscillator frequency can be adjusted. The higher the frequency, the faster the switching time.

Conclusion

The LM26001MXAX/NOPB is a DC-DC switching regulator ideal for applications with wide input voltages. This device can provide a fast transient response and is suitable for wearables and other battery-powered, demanding systems. It is designed to operate with a wide variety of packages and has an adjustable switching frequency up to 1MHz. Additionally, it is enabled with an Internal Soft Start in order to reduce the risk of undesired voltage spikes.
