Repair Your Avalon PSU: NCP1399AM NCP1399 High-performance Current Mode Controller

Repair your Avalon PSU with the NCP1399AM NCP1399 High-performance Current Mode Controller, a high-performance current mode controller for half-bridge resonant converters. This controller implements a 600V gate driver, simplifying the layout and reducing the external component count.

Safe Operation in Any Application: Overload Protection, Overcurrent Protection, Undervoltage Detection, Open Optocoupler Detection, and More

The NCP1399AM controller chip ensures safe operation in any application, offering overload protection, overcurrent protection against hard switching cycles, undervoltage detection, open optocoupler detection, automatic dead time adjustment, overvoltage (OVP), overtemperature (OTP) protection, and more.

With high-frequency operation from 20kHz to 750kHz, this current mode control scheme delivers unbeatable performance and efficiency. Its dedicated startup sequence ensures fast resonant tank stabilization, while skip mode operation improves light load efficiency. Off-mode operation ensures very low no-load consumption, making it the perfect choice for a wide range of applications.

Whether you're working on adapters and offline battery chargers, flat panel monitor power converters, industrial and medical power supplies, or other applications, the NCP1399AM NCP1399 High-performance Current Mode Controller is the perfect choice.

With latching or auto-recovery overload protection, latched or auto-recovery output short-circuit protection, latched inputs for critical fault conditions such as OVP or OTP, detuned switch protection, open feedback loop protection, accurate undervoltage protection, PFC-level operational control based on load conditions, start-up current source with very low leakage current, dynamic self-supply (DSS) operation in shutdown or fault mode, pin-to-adjacent pin/open pin failsafe, and lead-free devices, this controller delivers unbeatable performance and reliability.
