NCP1603 Datasheet, PDF (1/30 Pages) ON Semiconductor – PFC/PWM Combo Controller with Integrated High Voltage Startup and Standby Capability

NCP1603
PFC/PWM Combo Controller
with Integrated High
Voltage Startup and Standby
Capability
The NCP1603 is a Power Factor Correction (PFC) and Pulse Width
Modulation (PWM) combo controller. It offers extremely low
no−load standby power consumption that is suitable for the
low−power consumer markets. The key features of the device are
listed below.
Features
• Pb−Free Package is Available*
PFC Features
• Near−Unity Power Factor in Discontinuous and Critical Mode
(DCM and CRM)
• Voltage−Mode Operation
• Low Startup and Shutdown Current Consumption
• Programmable Switching Frequency for DCM
• Synchronization Capability
• Overvoltage Protection (107% of Nominal Output Level)
• Undervoltage Protection or Shutdown
(8% of Nominal Output Level)
• Programmable Overcurrent Protection
• Thermal Shutdown with Hysteresis (95/140°C)
• Undervoltage Lockout with Hysteresis (9.0/10.5 V)
PWM Features
• Integrated Lossless High Voltage Startup Current Source
• 100 kHz PWM Current−Mode Operation with Skipping Cycle
Capability During Standby Condition
• PFC Bias Voltage is Disabled in Standby Condition to Achieve
Extremely Low No−Load Standby Power Consumption
• Fault Protection Implemented by a Timer and Independent of Badly
Coupled Auxiliary Transformer Winding
• Primary Overcurrent Protection and Latched Overvoltage Protection
• Internal 2.5 ms Soft−Start
• "6.4% Frequency Jittering for Improved EMI Performance
• Latched Thermal Shutdown with Hysteresis (140/165°C)
• Undervoltage Lockout with Hysteresis (5.6/7.7/12.6 V)
Applications
• Notebook Adapters
• TV/Monitors
