ON Semiconductor NCP1423DMR2 - Compact, High-Efficiency DC-DC Converter

The NCP1423DMR2 from ON Semiconductor is a highly integrated DC-DC converter designed for portable applications that demand compact size and high efficiency. This step-up DC-DC converter is a perfect power solution for devices powered by single-cell alkaline, NiCd, NiMH, or single-cell Li-Ion batteries due to its ability to boost low input voltages to higher output voltages required by modern electronics.

With its high switching frequency of 1.2 MHz, the NCP1423DMR2 allows for the use of small, low-profile inductors and ceramic capacitors, which minimizes the overall footprint and height of the power supply design on the circuit board. This makes it an ideal choice for space-constrained applications such as handheld devices, wearable technology, and IoT devices.

The device features a True-Cutoff function that completely disconnects the load from the battery when the device is in shutdown mode, thereby conserving battery life. Additionally, the NCP1423DMR2 offers a Ring-Killer feature that reduces EMI by damping the inductor's ringing at the end of each switching cycle. This is particularly important in noise-sensitive applications.

With its high 0.8A current capability and an adjustable output voltage up to 5.0V, the NCP1423DMR2 can power a wide array of peripherals and core circuits. The converter also boasts a high efficiency of up to 96%, ensuring minimal power loss during conversion and extending battery life.

Protection features include thermal shutdown, which prevents damage from overheating, and under-voltage lockout (UVLO), which ensures the device operates only when the input voltage is within an acceptable range. The NCP1423DMR2 also includes a peak current limit to safeguard the device and the load from excessive input currents.

Offered in a compact Micro-8 package, the NCP1423DMR2 is a robust power management solution that combines performance, efficiency, and a small form factor to meet the needs of the latest portable electronic devices. ON Semiconductor's commitment to quality ensures that the NCP1423DMR2 delivers reliable and consistent performance for a wide range of applications.
