The NCP137AFCTCADJT2G is an integrated circuit (IC) component manufactured by ON Semiconductor. It is a high-performance Current Mode Controller designed for offline switched-mode power supplies (SMPS). Below are the key features and an overview of this IC component:
1. Overview:
- The NCP137AFCTCADJT2G is designed specifically for low power ac-dc adapters and chargers.
- It features a frequency modulation scheme that offers enhanced EMI performance.
- This IC component operates in a fixed frequency mode, making it suitable for flyback, isolated and non-isolated power supply topologies.
- The device incorporates a comprehensive set of protection features to ensure reliable operation and safeguard against fault conditions.
2. Key Features:
a. Intelligent System Management:
- The IC supports discontinuous and continuous conduction modes (DCM and CCM) to optimize power conversion efficiency across different load conditions.
- It includes a smart manner of frequency modulation that minimizes EMI emissions and enables compliance with regulatory standards.
b. Protections:
- The NCP137AFCTCADJT2G provides a suite of protections to enhance system reliability and prevent damage from fault conditions.
- It features cycle-by-cycle current limit protection, which disables the switching transistor if the current limit is exceeded.
- Built-in Over Temperature Protection (OTP) ensures that the IC shuts down if it surpasses its rated temperature, preventing thermal damage
