Product Overview
NCP12510: Current-Mode PWM Controller for Off-line Power Supplies
For complete documentation, see the data sheet.
The NCP12510 is a highly integrated PWM controller capable of
delivering a rugged and high performance offline power supply in a
tiny TSOP-6 package. With a voltage supply range up to 35 V, the
controller hosts a jittered 65-kHz or 100-kHz switching circuitry
operated in peak current mode control. When the power on the
secondary side starts decreasing, the controller automatically folds
back its switching frequency down to a minimum level of 26 kHz. As
the power further goes down, the part enters skip cycle while limiting
the peak current. The controller has integrated protections such as Over Power Protection (OPP), Over Voltage Protection (OVP)
and short-circuit protections. NCP12510 is improved and pin compatible controller based on very popular flyback controller
NCP1250.
Features Benefits
• Frequency Foldback down to 26 kHz and Skip-Cycle in light
load conditions
• High efficiency in light load conditions
• Non-dissipative internal and adjustable Over Power
Protection (OPP) circuits
• Limits maximum delivered power without affecting standby
performance
• Frequency jittering from full load to skip-cycle • Improved EMI performance
• Rich Set of Integrated Protections: Pre-short, OPP, OVP,
OCP, SCP, OTP with Auto-Recovery or Latched Options.
• Simple implementation of required protection functions
• Improved IC Power Consumption • Higher efficiency and lower No-Load Power Loss
• Internal Ramp Compensation • Reduces the number of external components
• High Robustness and High ESD Capabilities • Robust power supply with up to 4KV ESD
Applications End Products
• Offline Adapters • Notebooks and Tablets
• AC-DC converters • General External AC-DC Adapters
• Printers
• Set-top Boxes
