NB649EQJ-LF-Z

PMIC - Voltage Regulators - DC DC Switching Regulators

The NB649EQJ-LF-Z is a DC DC switching regulator module, designed to responsibly regulate the voltage across a wide range of input supply voltages. The NB649EQJ-LF-Z is primarily used in applications like automotive electronics which require the voltage to be precisely regulated in order to maintain an optimal performance level of the connected electronic components and devices. Additionally, the module features a built-in protection circuit which helps to reduce the risk of damage from overload, short-circuits, and over-temperatures.

Application Field and Working Principle

The NB649EQJ-LF-Z offers a wide range of application fields. The module can be used in automotive applications, where devices and components like sensors, servos, and actuators require reliable and stable voltage levels. Additionally, the NB649EQJ-LF-Z can be used in industrial settings, providing reliable and regulated voltage to a wide range of devices and equipment. The NB649EQJ-LF-Z also finds applications in instrumentation and control systems, where stable voltage is an absolute necessity.

The working principle of the NB649EQJ-LF-Z is based on Pulse Width Modulation (PWM). This technique is a form of regulation that uses a square wave of varying duty cycle. The ratio of the duty cycle of the output square wave to the duty cycle of the input signal (known as the “duty cycle ratio”) determines the amount of voltage regulation across the output. The NB649EQJ-LF-Z uses an input voltage range of 2.4V to 24V, and an output voltage range of 1.2V to 24V.

The module has a wide operating temperature range from -40°C to +105°C, and features an over-temperature protection circuit which will shut the system down in case of abnormally high temperature. Additionally, the module is locked and can be unlocked by means of a software dedicating command.

Advantages of the NB649EQJ-LF-Z

The NB649EQJ-LF-Z has several advantages over other DC DC switching regulator solutions. The most important of these are:

• High efficiency – up to 95% at full load and low dropout.
• Fast transient response.
• Integrated protection from overload, short-circuit and over-temperature.
• Wide operating temperature range.
• Software unlock.

The NB649EQJ-LF-Z is also designed with a small form factor in mind, allowing it to fit in almost any system or application. This makes it an excellent choice for large-scale deployment.

Conclusion

The NB649EQJ-LF-Z is an excellent choice for voltage regulation in applications ranging from automotive devices to industrial equipment and instrumentation. Its unique features and wide operating temperature range make it a reliable, accurate, and cost-effective choice. With integrated protections, a small form factor and high efficiency, the NB649EQJ-LF-Z is the ideal DC DC switching regulator solution.
