onsemi NCP1399 High-Performance Current Mode Controllers
onsemi NCP1399 High-Performance Current Mode Controllers are for half-bridge resonant converters and implement 600V gate drivers, simplifying layout and reducing the external component count. The device has a built-in Brown-Out input function that eases implementation of the controller in all applications. The onsemi NCP1399 features a dedicated output to drive the PFC controller in applications where a PFC front stage is needed. This feature, together with a dedicated skip mode technique, further improves the light-load efficiency of the whole application.
Features
- High-frequency operation from 20kHz up to 750kHz
- Current mode control scheme
- Automatic dead-time with maximum dead-time clamp
- Dedicated startup sequence for fast resonant tank stabilization
- Skip mode operation for improved light-load efficiency
- Off-mode operation for extremely low no-load consumption
- Latched or auto-recovery overload protection
- Latched or auto-recovery output short circuit protection
- Latched input for severe fault conditions, e.g., OVP or OTP
- Out of resonance switching protection
- Open feedback loop protection
- Precise Brown-Out protection
- PFC stage operation control according to load conditions
- Startup current source with extremely low leakage current
- Dynamic Self-Supply (DSS) operation in off-mode or fault modes
- Pin to adjacent pin / open pin fail safe
- These are Pb-free devices
Applications
- Adapters and offline battery chargers
- Flat-panel display power converters
- Computing power supplies
- Industrial and medical power sources
