Description and Introduction

200mA, PFM Step-Up Micropower Switching Regulator # Introduction to the NCP1402SN33T1 Voltage Regulator  

The NCP1402SN33T1 is a high-efficiency, step-up (boost) DC-DC switching regulator designed to provide a stable 3.3V output from low input voltages. This component is particularly useful in battery-powered applications where maintaining consistent voltage levels is critical, such as portable electronics, IoT devices, and energy harvesting systems.  

With an input voltage range of 0.8V to 4.5V, the NCP1402SN33T1 efficiently boosts power from single-cell batteries (e.g., alkaline or NiMH) to the required output. Its integrated switching MOSFET minimizes external component count, simplifying PCB design while improving reliability. The regulator operates at a fixed switching frequency, reducing electromagnetic interference (EMI) and ensuring predictable performance.  

Key features include low quiescent current, enhancing battery life in standby modes, and automatic pulse-frequency modulation (PFM) for improved efficiency at light loads. The compact SOT-23-5 package makes it suitable for space-constrained designs.  

Engineers favor the NCP1402SN33T1 for its balance of efficiency, compact size, and ease of integration, making it a versatile solution for low-power, battery-operated applications requiring stable voltage regulation.

Description and Introduction

200mA, PFM Step-Up Micropower Switching Regulator # Introduction to the NCP1402SN33T1 Voltage Regulator  

The NCP1402SN33T1 is a high-efficiency, step-up (boost) DC-DC switching regulator designed to provide a stable 3.3V output from low input voltages. This compact and versatile component is commonly used in battery-powered applications where efficient power conversion is essential, such as portable electronics, IoT devices, and wireless sensors.  

With an input voltage range of 0.8V to 5.0V, the NCP1402SN33T1 is particularly suitable for single-cell or dual-cell alkaline, NiMH, or lithium-based battery systems. Its integrated switching MOSFET and synchronous rectification minimize external component count, simplifying design while improving efficiency. The regulator operates at a fixed switching frequency, ensuring predictable performance and reduced electromagnetic interference (EMI).  

Key features include a low quiescent current, enabling extended battery life in standby modes, and an automatic pulse-frequency modulation (PFM) mode that enhances efficiency at light loads. The device also incorporates built-in protections such as overcurrent and thermal shutdown, ensuring reliable operation under varying conditions.  

Available in a space-saving SOT-23-5 package, the NCP1402SN33T1 is an excellent choice for designers seeking a compact, efficient, and reliable power management solution for low-voltage applications.
