NCP12700 是一款固定频率、峰值电流模式 PWM 控制器,具有实施单端功率转换器拓扑结构所需的所有功能。该器件具有高电压启动特性,能够在很宽的输入范围内运行 (9 – 120/200 V MSOP10/WQFN10) 并提供至少 20 mA 电源,在启动期间为 VCC 提供临时偏置。该控制器提供可调节软启动、输入电压 UVLO 保护以及可调节的过功率保护电路,会在输入电压提高时限制电路的总功率能力,简化系统散热设计。UVLO 还具有一个关断比较器,允许外部型号禁用开关,将控制器带入低静止状态。
特性   优势
     
  • Wide Input Range (9 – 120/200 V; MSOP10/WQFN10)
 
  • Simplify design and reduce BOM cost
  • Current Mode Control with Integrated Slope Compensation
 
  • No sub-harmonic oscillation in CCM mode .
  • Single Resistor Programmable Oscillator
 
  • Easy and flexible
  • 1 A / 2.8 A Source / Sink Gate Driver
 
  • Drive any type of MOSFET's
  • Input Voltage UVLO with Hysteresis
 
  • To protect the design or bring the controller into a low quiescent state
  • Several Fault Protections:
    - User Adjustable Over-Power Protection
    - Overload Protection with 30 ms Overload Timer
    - NTC-Compatible Fault Interface for Thermal Protection
    - Output OVP Fault Interface
