Description

The ON Semiconductor NCP1377PG is a highly integrated PWM current-mode controller designed for high-performance power supply applications. This advanced controller is engineered to deliver precise power regulation, enhanced system reliability, and improved energy efficiency, making it an ideal choice for a wide range of power conversion tasks.

Featuring a fixed-frequency operation with a frequency jittering capability, the NCP1377PG helps in reducing electromagnetic interference (EMI), allowing for a more stable operation across different environments and applications. Its current-mode control provides fast transient response and excellent loop stability.

Key Features:

  • Current-Mode Control for Improved Response Time and Stability
  • Frequency Jittering for Reduced EMI
  • High-Voltage Startup Current Source for Quick Power-Up
  • Auto-Recovery Overvoltage and Overload Protections
  • Adjustable Peak Current Limit
  • Soft-Skipping Technology to Enhance Efficiency at Light Loads
  • Under-Voltage Lockout (UVLO) with Hysteresis
  • Low Standby Power Consumption

The device incorporates a high-voltage startup current source that enables the power supply to start up under full-load conditions without the need for an additional standby transformer. This feature contributes to reducing the overall system cost and complexity.

Protection features are paramount in the NCP1377PG design. It includes auto-recovery overvoltage protection (OVP) and overload protection (OLP), ensuring the power supply and the end application are safeguarded against various fault conditions. The adjustable peak current limit allows for customized protection settings based on specific application requirements.

Additionally, the NCP1377PG's soft-skipping technology ensures high efficiency even at light loads by skipping unnecessary switching cycles, thus reducing switching losses. This contributes to the overall energy-saving characteristics of the device, especially important in applications where power efficiency is critical.

With its comprehensive set of features and protections, the ON Semiconductor NCP1377PG is a robust and versatile solution for a variety of power supply designs, including adapters, open-frame power supplies, and offline battery chargers.
