Description and Introduction

200 mA, PFM Step−Up Micropower Switching Regulator The **NCP1402SN33T1G** is a high-efficiency, step-up DC-DC converter designed for low-power applications requiring stable voltage regulation. This compact IC integrates a fixed-frequency oscillator, power switch, and feedback control to deliver a regulated 3.3V output from input voltages as low as 0.8V.  

Ideal for battery-powered devices, the NCP1402SN33T1G features low quiescent current, making it suitable for portable electronics such as sensors, wearables, and IoT modules. Its ability to operate with minimal external components simplifies design while maintaining efficiency across varying load conditions.  

Key specifications include an output current of up to 200mA, a switching frequency of 1.2MHz, and built-in protections such as overcurrent and thermal shutdown. The device is housed in a space-saving SOT-23-5 package, enabling integration into space-constrained designs.  

Engineers favor the NCP1402SN33T1G for its reliability, low-noise performance, and ability to extend battery life in energy-sensitive applications. Whether used in medical devices, consumer electronics, or industrial systems, this converter provides a dependable power solution with minimal design complexity.  

For detailed performance curves and application guidelines, consult the official datasheet to ensure optimal implementation in your circuit design.
