Power supplier technology has come a long way in recent decades, providing users with access to a variety of innovative and reliable products for a variety of applications. The NCP1219BD65R2G, an integrated circuit from ON Semiconductor, was designed with an eye towards energy efficiency. This component falls under the classification of PMIC – AC DC converters, Offline switchers, providing users with a versatile power solution applicable to virtually any design.

The NCP1219BD65R2G device is a low noise Buck regulator optimized for LED lighting. It is capable of delivering 500mA or 1A, depending on the selection of an external resistor. The device features built in overvoltage protection, hysteretic control, and programmable soft-start functionality. The device can function as a standalone Buck regulator, or as a single feedback Buck controller. In either mode of operation, the device supports the use of synchronous rectification, reducing conduction losses and improving overall efficiency.

If the NCP1219BD65R2G is used as a standalone regulator, the output voltage is pre-set by an internal resistor divider network. In this mode, stable operation is ensured due to the hysteretic control loop and current mode control scheme. In addition, the device has two types of overload protection; “VUPS” (voltage under-load protection) and “VUPS+” (over-load current protection). This combination provides robust protection against under-voltage and over-current conditions, keeping the system safe from damage.

If the NCP1219BD65R2G is used as a single feedback Buck controller, the output voltage is established via an external resistor divider connected between the “FB” (feedback) and “GND” pins of the device. In this mode, the high accuracy of the control loop is ensured due to the hysteretic control loop, along with a programmable soft-start and frequency synchronization features.

The NCP1219BD65R2G is a highly integrated device, offering maximum flexibility and performance in a small package. It is suitable for applications requiring an efficient and cost-effective supply, such as LED lighting and dimming, LED backlight, LED displays, and more. The device has excellent EMI performance, with a low noise, low ripple, and low EMI noise profile. The device also supports a wide range of operating temperatures, from -40℃ to +125℃, making it suitable for a wide range of applications.

In addition to its integrated Buck regulator and discrete feedback controller, the NCP1219BD65R2G features protection against overvoltage, undervoltage, and overcurrent conditions. This makes the device highly reliable and well-suited for a variety of applications. The device has low operating current, making it suitable for battery-powered applications, as well as for mobile and automotive applications.

The NCP1219BD65R2G is an excellent choice for a wide range of applications. Its flexible design, high performance, and excellent protection features make it an ideal choice for applications requiring efficient power delivery, long life, and high reliability. ON Semiconductor’s NCP1219BD65R2G is the perfect choice for your next design.
