BD9718G-TR

BD9718G-TR Application Field and Working Principle

The BD9718G-TR is a DC-DC switching regulator designed to meet the industrial requirements of low output voltage DC-DC regulated power supply devices. This device is part of a PMIC range of voltage regulators and DC-DC switching regulators.

BD9718G-TR devices offer low noise control, low output voltage ripple, high efficiency and excellent transient response. These voltage regulators are used in a range of applications requiring an output voltage of up to 25V, such as LED drivers, PDC battery charge controllers, LED displays, LED lighting etc. The device can also be used for other industrial applications as long as the input/output Voltages and current requirements are met.

The BD9718G-TR\'s working principle is quite simple. The regulator is controlled by a pulse-width modulation (PWM) signal, generated by a compatible internal or external reference oscillator. This signal varies the duty cycle which adjusts the output voltage. The BD9718G-TR can regulate from a wide input voltage range of 4.5V to 34V, with the output voltage adjustable between 0.5V and 25V with a maximum output current of up to 1A.

The BD9718G-TR also contains a built-in Under Voltage Lockout (UVLO) circuit that prevents faulty environmental conditions and over/underload conditions from damaging the device. The device also has over-voltage protection and a thermal protection feature that shuts down the device if temperature becomes too high. This means the BD9718G-TR can provide a reliable and stable output even in demanding and unpredictable environments.

In conclusion, the BD9718G-TR is a suitable DC-DC switching regulator for various industrial applications requiring an output voltage of up to 25V with high efficiency, low output voltage ripple, low noise control and excellent transient response. The device is also protected from environmental conditions and over/underloads, making it a reliable, stable and cost-effective power solution for a wide range of applications.
