PMIC-Voltage Regulators-Special Purpose

Analog Devices’ LNBH23TQTR is a member of the special purpose voltage regulator family. It is a high-performance, low-noise DC/DC modular switching step-down regulator specifically designed to dissipate harmonic components generated by DC motors and to improve the efficiency of power cables.

The LNBH23TQTR is designed for multiple-load applications and is capable of outputting both a regulated voltage and an unregulated voltage simultaneously. This makes it an ideal choice for applications where an adjustable voltage is needed, such as for motor control, power management, and power conversion.

Application field

The LNBH23TQTR is an ideal choice for applications requiring an adjustable voltage, including:

• Motor control
• Robotics
• Power management
• Communication systems
• Industrial automation
• Power conversion

Working principle

The LNBH23TQTR utilizes a switching step-down regulator architecture, including a PMOS power transistor and an integrated demagnetization circuit. It is designed to convert incoming DC power into a regulated output, which can be programmed to a desired voltage and current through external resistors.

Once the voltage and current have been set, the switching regulator architecture begins to regulate the output voltage by modulating the power transistor based upon the sensed output current. In addition, the integrated demagnetization circuit reduces harmonic components generated by DC motors and improves the efficacy of power cables.

The LNBH23TQTR is designed for multiple-load applications and is capable of providing multiple, simultaneous regulated and unregulated outputs. When multiple outputs are in use, it is possible to disable any output by setting its output voltage to zero. This enables the regulator to manage the output voltages more accurately and efficiently.

The LNBH23TQTR is an adjustable voltage regulator that is specifically designed to meet the stringent requirements of motor control, robotics, power management, communications, industrial automation, and power conversion.
