The NCP13992 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 NCP13992 features a dedicated output to drive the

PFC controller. This feature together with quiet skip mode technique

further improves light load efficiency of the whole application. The

NCP13992 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,

over?voltage (OVP) and over?temperature (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

? Light Load Operation Mode for Improved Efficiency

? Quiet Skip Operation Mode for Minimize Transformer Acoustic Noise

? 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

NCP13992AK屬于集成電路（IC） > AC DC 轉(zhuǎn)換器，離線開關(guān)。安森美半導(dǎo)體公司制造生產(chǎn)的NCP13992AKAC DC 轉(zhuǎn)換器，離線開關(guān)該系列是元器件級控制產(chǎn)品，用于構(gòu)建將交流市電轉(zhuǎn)換為直流電（通常電壓大幅降低）的設(shè)備。集成和未集成系統(tǒng)主要開關(guān)元件的器件均包括在內(nèi)。由于高輸入輸出電壓比，以及此類系統(tǒng)中通常需要隔離，這些器件通常與外部變壓器配合使用。盡管通常使用定制變壓器來實現(xiàn)此用途，但也有許多專門用于此用途的庫存產(chǎn)品，請參見“開關(guān)轉(zhuǎn)換器，SMPS 變壓器”標(biāo)題。
