The LM21212MHE-2/NOPB is a DC-DC switching regulator that solves design challenges related to layout, power dissipation and size. This device can output either a positive or negative voltage with adjustable voltage/current regulation. It is designed for high density and performance with low external component count. The LM21212MHE-2/NOPB is a synchronous step-down (buck) converter that can be configured for multiple output voltages. It includes a Synchronous Rectified MOSFET to provide good efficiency and control.

This device is suitable for a wide range of applications, including high current point of load (PoL) regulation, buck-boost converters, inverters, and voltage doubling. Applications include industrial, telecommunications, automotive and automotive systems such as Li-ion battery management, motor control and power supplies.

The LM21212MHE-2/NOPB can be configured to provide a constant voltage output or a current output using either a single or dual mode control configuration. The device can also operate in an adjustable current output mode to rapidly transfer current from one voltage source to another.

The LM21212MHE-2/NOPB employs an internal high-speed PWM controller with integrated fault-protection circuitry, allowing for synchronous operation up to 2MHz. The device\'s wide input voltage range of 4 to 40V makes it suitable for automotive, industrial, and other high-input voltage applications. The device also features over-temperature, over-voltage, and over-current protection to protect it from damage due to excessive temperatures, voltages, or currents. It also features a Programmable Soft-Start to reduce inrush current during start-up and reduce stress on power supplies.

The LM21212MHE-2/NOPB is capable of providing very high current and power output levels. The device includes a high-speed PWM controller that operates at switching frequencies up to 2MHz. The output voltage (VOUT) is adjustable using a single resistor or an external voltage. It also features automatic power-saving mode to reduce power consumption during light loads.

The LM21212MHE-2/NOPB can be configured to provide a constant voltage output with either a single or dual mode control. In single mode control the output voltage is adjusted by applying a single resistor. In dual mode control the output voltage is adjusted by applying a voltage to one of the two adjustable terminals. Additionally, the device can be configured to provide a current output or restricted current output with a single adjustable external resistor. The device utilizes an internal MOSFET driver to control the output current, improving efficiency and reducing external component counts.

The LM21212MHE-2/NOPB is ideal for applications requiring low noise, low power consumption, high efficiency and high current switching power conversion. Its features make it suitable for a wide range of applications such as point of load (PoL) regulation, buck-boost converters, inverters, and voltage doubling. It is also well-suited for automotive applications such as Li-ion battery management and motor control, as well as industrial, telecommunications, and other high-input voltage applications.
