Introduction
The NCP1250 implements a standard current mode architecture where the switch−off event is dictated by the peak current setpoint. This component represents the ideal candidate where low part−count and cost effectiveness are the key parameters, particularly in low−cost ac−dc adapters, open−frame power supplies etc. Capitalizing on the NCP120X series success, the NCP1250 packs all the necessary components normally needed in today modern power supply designs, bringing several enhancements such as a non−dissipative OPP.
Features
- Fixed−Frequency 65 or 100 kHz Current−Mode Control Operation
- Internal and Adjustable Over Power Protection (OPP) Circuit
- Frequency Foldback Down to 26 kHz and Skip−Cycle in Light Load Conditions
- Internal Ramp Compensation
- Internal Fixed 4 ms Soft−Start
- 100 ms Timer−Based Auto−Recovery Short−Circuit Protection
- Frequency Jittering in Normal and Frequency Foldback Modes
- Option for Auto−Recovery or Latched Short−Circuit Protection
- OVP Input for Improved Robustness
- Up to 28 V VCC Operation
- +300 mA/−500 mA Source/Sink Drive Capability
- Less than 100 mW Standby Power at High Line
- EPS 2.0 Compliant
- These are Pb−Free Devices
Applications
- ac−dc Converters for TVs, Set−top Boxes and Printers
- Offline Adapters for Notebooks and Netbooks
