Power management integrated circuits (PMICs) are essential components in most microelectronic devices, capable of providing the right level of power supply reliability and efficiency required to keep sensitive electronic components operational. One particular PMIC that can be used to great effect is the LM10000SD/NOPB, a specialized power management integrated circuit (PMIC) made by Texas Instruments and offered as an industrial-grade solution.

The LM10000SD/NOPB builds on an earlier version of TI\'s LM10000 family, offering extended parameters that support much higher input voltages, higher output currents and improved accuracy and stability. The LM10000SD/NOPB stands out for its small size—only 8-lead DIP packages in a low profile design, making it ideal for circuit boards and other tight space applications. The device can be used in many different industries and applications, including industrial and medical equipment, smart metering, lighting and other IoT solutions.

SAFE AND RELIABLE POWER SUPPLY

The LM10000SD/NOPB ensures a safe and reliable power supply by providing adjustable voltage regulation and precise current regulation. The device has a low minimum dropout (LDO) voltage of 1.2V and can support input voltages up to 40 V. An internal voltage divider lets the LM10000SD/NOPB maintain a precise voltage even with different types of load conditions. The device also offers current sensing and current limit functions, which protect the output section against short circuits and over current conditions.

The LM10000SD/NOPB also provides short-circuit protection, overvoltage protection and over-temperature protection. All these features make the LM10000SD/NOPB an ideal choice for use in high reliability industrial and medical applications.

WORKING PRINCIPLE

The LM10000SD/NOPB operates using an error amplifier with a low power operational amplifier, a voltage reference, a voltage divider and a set of sense and control resistors. When the output voltage approaches the required level, the error amplifier compares the voltage reference voltage to the output voltage, and adjusts the amount of current accordingly. The LM10000SD/NOPB can provide both constant voltage operation and constant current operation, and can work with either single ended or differential operation.

ADVANCED FEATURES

The LM10000SD/NOPB has several advanced features that make it one of the most versatile and powerful power management ICs on the market. The device has an adjustable output voltage range of 0.5–40 V, and can support loads of up to 5A. The device also features an adjustable input voltage range of 4.5 – 40V and an adjustable output voltage accuracy of up to ±2%.

Other features include an internal clock signal generator, an internal power supply monitor, an adjustable current-limit threshold, and two shutdown modes. The device also has a low quiescent current of 2 mA and a low dropout voltage of 0.1V.

USES AND APPLICATIONS

As a specialized power management integrated circuit, the LM10000SD/NOPB is used to deliver safe and precise power supply regulation and current regulation. The device is commonly used in industrial, medical and smart metering applications to provide safe and efficient power supply to sensitive electronic components. Additionally, due to its low quiescent current and small form factor, the LM10000SD/NOPB is suited for battery-powered applications and other portable products.

In general, the LM10000SD/NOPB offers a complete solution for precise power supply regulation in a wide variety of applications and industries. With its adjustable voltage and current regulation, low quiescent current, and other advanced features, the device is an ideal choice for reliable and safe power management applications.
