Description
High Performance Current Mode Resonant Controller
with Integrated HighVoltage Drivers.
The NCP1399 is a high performance current mode controller for half
bridge resonant converters. This controller implements 600 V gate
drivers, simplifying layout and reducing external component count. The
built?in Brown?Out input function eases implementation of the
controller in all applications. In applications where a PFC front stage is
needed, the NCP1399 features a dedicated output to drive the PFC
controller. This feature together with dedicated skip mode technique
further improves light load efficiency of the whole application. The
NCP1399 provides a suite of protection features allowing safe operation
in any application. This includes: overload protection, over?current
protection to prevent hard switching cycles, brown?out detection, open
optocoupler detection, automatic dead?time adjust, overvoltage (OVP)
and overtemperature (OTP) protections
Features
• High?Frequency Operation from 20 kHz up to 750 kHz
• 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
Typical Applications
• Adapters and Offline Battery Chargers
• Flat Panel Display Power Converters
• Computing Power Supplies
• Industrial and Medical Power Sources
