Description and Introduction

100mA, Fixed Frequency PWM Step-Up Micropower Switching Regulator The **NCP1400ASN50T1** is a high-performance, step-up DC-DC converter designed to efficiently boost low input voltages to higher output levels. This compact and versatile IC is commonly used in battery-powered applications where stable voltage regulation is critical, such as portable electronics, IoT devices, and energy harvesting systems.  

With an input voltage range of **0.8V to 3.6V**, the NCP1400ASN50T1 can deliver a fixed **5.0V output**, making it ideal for powering microcontrollers, sensors, and other low-power components. Its integrated switching MOSFET ensures high efficiency while minimizing external component count, simplifying PCB design.  

Key features include a low **0.3V startup voltage**, enabling operation from nearly depleted batteries, and a **1MHz switching frequency**, which reduces inductor size for space-constrained designs. The device also incorporates **soft-start functionality** to limit inrush current and **thermal shutdown protection** to safeguard against overheating.  

Available in a **SOT-23-5 package**, the NCP1400ASN50T1 offers a balance of performance and compactness, making it a reliable choice for engineers seeking an efficient, low-cost power management solution. Its robust design ensures stable operation across varying load conditions, enhancing system reliability in demanding applications.

Application Scenarios & Design Considerations

Alternative Part Number

  • TPS61200DRLR --: Boost converter with integrated switch, similar step-up function and low input voltage operation, widely available and well documented.
  • LTC3525ESC6-5 --: Fixed 5V output boost converter in a small package, matches the 5.0V output of the original and offers high efficiency at low input voltages.
  • MCP1640T-I/CHY --: Low-voltage boost converter with 5V output option, pin-compatible style SOT-23 package and good substitute for small battery-powered step-up designs.
  • MCP1640BT-I/CHY --: Low-voltage boost regulator with integrated switch, comparable input range and output current, easy drop-in for portable designs.
