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

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

Typical Applications

• Adapters and Offline Battery Chargers

• Flat Panel Display Power Converters

• Computing Power Supplies

• Industrial and Medical Power Sources
