High Performance Current
Mode Resonant Controller
with Integrated High-
Voltage 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
builtâin BrownâOut 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, overâcurrent
protection to prevent hard switching cycles, brownâout detection, open
optocoupler detection, automatic deadâtime adjust, overvoltage (OVP)
and overtemperature (OTP) protections.
Features
⢠HighâFrequency Operation from 20 kHz up to 750 kHz
⢠Current Mode Control Scheme
⢠Automatic Deadâtime with Maximum Deadâtime Clamp
⢠Dedicated Startup Sequence for Fast Resonant Tank Stabilization
⢠Skip Mode Operation for Improved Light Load Efficiency
⢠Offâmode Operation for Extremely Low Noâload Consumption
⢠Latched or AutoâRecovery Overload Protection
⢠Latched or AutoâRecovery 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 BrownâOut Protection
⢠PFC Stage Operation Control According to Load Conditions
⢠Startup Current Source with Extremely Low Leakage Current
⢠Dynamic SelfâSupply (DSS) Operation in Offâmode or Fault Modes
⢠Pin to Adjacent Pin / Open Pin Fail Safe
Typical Applications
⢠Adapters and Offline Battery Chargers
⢠Flat Panel Display Power Converters
⢠Computing Power Supplies
⢠Industrial and Medical Power Sources
