ON Semiconductor NCP1402SN30T1 Step-Up DC-DC Converter

The NCP1402SN30T1 is a highly efficient, compact DC-DC converter from ON Semiconductor, designed to step up lower voltages to a fixed 3.0V output. This versatile component is an ideal solution for battery-powered applications, where extending the battery life is crucial, and space on the PCB is at a premium.

With a start-up voltage as low as 0.8V and an operating range from 0.9V to 3.0V, the NCP1402SN30T1 is particularly suitable for devices powered by single-cell batteries. It can efficiently convert the diminishing voltage of a discharging battery to a stable 3.0V required by many electronic circuits, making it perfect for portable devices, such as handheld medical instruments, wearables, and IoT sensors.

This step-up converter features a high switching frequency of 100kHz, which allows for the use of small, low-cost inductors and capacitors, thus reducing the overall footprint and bill of materials. The NCP1402SN30T1 also incorporates an automatic pulsing frequency modulation scheme to maximize efficiency over a wide range of load conditions.

The built-in over-temperature and under-voltage lockout protections ensure safe operation under abnormal conditions. The device also provides a true cut-off function when disabled, minimizing battery drain when not in active use.

The NCP1402SN30T1 is offered in a space-saving 5-pin TSOP package, making it easy to integrate into space-constrained designs. Its high power efficiency, low quiescent current, and minimal external component requirements make it an excellent choice for engineers looking to optimize their power management solutions while maintaining a small form factor.

Overall, the NCP1402SN30T1 from ON Semiconductor provides designers with a reliable and efficient voltage step-up solution that is both easy to implement and capable of delivering consistent performance, which is essential for maintaining the longevity and reliability of battery-powered applications.
