NCP1399AA 14 pin
14-pin NCP1399AA chip, suitable for power supply and Hach boards, 600V driver, is a current mode resonant controller.
NCP1399AA is a high-performance current mode controller for half-bridge resonant converters. The controller implements a 600 V gate driver, simplifies the layout and reduces the number of external components. The built-in Brown-Out input function makes it easy to implement the controller in all applications. In applications that require a PFC front stage, NCP1399 has a dedicated output to drive the PFC controller. This function, together with the dedicated skip mode technology, further improves the light load efficiency of the entire application. This NCP1399 provides a series of protection functions, which can operate safely in any application. This includes: overload protection, over-current protection against hard switching cycles, power-down detection, open-circuit detection of optocoupler, automatic no-load time adjustment, over-voltage (OVP) and over-temperature (OTP) protection.
• High frequency operation from 20 kHz to 750 kHz
• Current mode control scheme
•Automatic dead zone with maximum dead zone clamp
• Dedicated startup sequence can realize the stability of fast resonance tank
• Skip mode operation can improve light load efficiency
• Non-mode operation with very low no-load power consumption
•Latch or automatically restore overload protection
• Latch or automatic recovery output short circuit protection
• Latch input for severe fault conditions, such as OVP or OTP
• Detuned switch protection
• Open loop feedback protection
• Precise power failure protection
• PFC-level operation control according to load conditions
• Starting current source with extremely low leakage current
•Dynamic self-powered (DSS) operation in shutdown mode or failure mode
• Pins are fixed to adjacent pins/open-circuit pins fail-safe
• These are lead-free devices
• Adapter and offline battery charger
• Flat panel display power converter
• Calculate power
• Industrial and medical power supply
