ON Semiconductor NCP1337DR2G - Power Management IC
The NCP1337DR2G is a cutting-edge PWM controller from ON Semiconductor that combines a true current mode modulator and a demagnetization detector to ensure full borderline/critical Conduction Mode in any load/line conditions together with minimum drain voltage switching (Quasi-Resonant operation).
Designed for high-performance power conversion applications, the NCP1337DR2G is ideal for switch mode power supplies (SMPS) used in a variety of devices such as flat-panel televisions, desktop monitors, and other consumer electronics that demand high efficiency and reliability. The integration of a high-voltage startup FET ensures that the power supply starts up in a controlled manner, contributing to the product's robustness and longevity.
The NCP1337DR2G features several protective elements that make it a reliable choice for safety-critical applications. These include an Auto-Recovery Overvoltage Protection (OVP) and an Overload Protection (OLP), which help to prevent damage to the power supply and the end device in the event of a fault condition. Additionally, the Frequency Foldback and Dynamic Self-Supply (DSS) limit the power dissipation in the controller and the system as a whole, enhancing the overall efficiency.
This PWM controller also offers a Skip Cycle capability at low peak currents, which significantly improves the standby power consumption, making devices more energy-efficient and compliant with energy-saving standards. Its built-in frequency jittering reduces EMI emissions, and the adjustable peak current limit allows for a flexible design that can be tailored to specific application requirements.
The NCP1337DR2G is available in a compact SOIC-7 package, facilitating integration into space-constrained applications. With its advanced features and ON Semiconductor's reputation for quality, this PWM controller is an excellent choice for designers looking to optimize their power management solutions.
