The NCP1205DR2G from ON Semiconductor is a single-ended PWM controller featuring Quasi-Resonant (QR) operation and soft frequency foldback. This device is designed for offline AC/DC adapters and power supplies, targeting applications that meet stringent standby power recommendations.
Key electrical specifications include an operating voltage range of 8.0 V to 30 V and an operating frequency between 90 kHz and 125 kHz. It incorporates Current Mode Control and offers fault protection features such as current limiting, overvoltage protection, and short-circuit protection. The controller also includes an internal 200 ns leading edge blanking on the current sense.
Packaged in a 16-SOIC (0.154", 3.90mm Width) surface mount package, the NCP1205DR2G is suitable for various power supply designs. Its features like natural drain valley switching contribute to lower EMI, while smooth frequency foldback ensures low standby power and minimum ripple at light loads. The device is designed for isolated flyback topologies.
This component is ideal for high power AC/DC adapters for notebooks, offline battery chargers, and power supplies for consumer electronics like DVD players and TVs. Its robust design and integrated features make it a reliable choice for modern power conversion systems.
