ON Semiconductor NCP1410DMR2 Step-Up DC-DC Converter

The ON Semiconductor NCP1410DMR2 is a highly efficient, fixed-frequency, step-up DC-DC converter designed to operate as a power supply for battery-powered devices. This compact and versatile component is ideal for applications that require a small footprint and minimal external components, making it a perfect solution for portable electronics, such as personal digital assistants (PDAs), digital cameras, and other handheld devices.

The NCP1410DMR2 operates at a switching frequency of 100kHz, which allows for the use of small, low-cost inductors and capacitors while maintaining high efficiency and low noise characteristics. This integrated circuit features a 0.8V start-up voltage, which is particularly beneficial for single-cell battery applications where the available voltage can be as low as the battery's end-of-discharge voltage.

With its high efficiency of up to 90%, the NCP1410DMR2 conserves battery life by minimizing power loss during conversion. Its output voltage is preset at 3.3V, delivering a stable supply for consistent device performance. Additionally, the NCP1410DMR2 includes a built-in power-saving mode that reduces quiescent current to just 5µA during light load conditions, further extending battery life.

The device's protection features are robust, including under-voltage lockout (UVLO), which ensures that the converter operates only when the input voltage is within an acceptable range. Over-temperature protection safeguards the device against excessive heat, while the current limit feature prevents damage from over-current conditions.

Engineered in a compact Micro-8 package, the NCP1410DMR2 is designed for space-constrained applications. Its small form factor, combined with a minimal external component count, contributes to a simplified design process and reduced overall system size.

In summary, the ON Semiconductor NCP1410DMR2 is a reliable and efficient solution for boosting battery voltages in portable electronic devices. Its low start-up voltage, high efficiency, and power-saving features make it an excellent choice for designers looking to maximize battery life while maintaining consistent device operation.
