Overview

The NCP1294 fixed frequency flyback PWM controller contains all of the features necessary for basic flyback, forward or boost operation. This PWM controller has been optimized for high frequency primary side control operation. In addition, this device includes such features as: Soft Start, accurate duty cycle limit control, less than 50uA startup current, over and under voltage protection, and bidirectional synchronization. The NCP1294 is available in a SOIC-16 and TSSOP-16 surface mount packages.

  • MPPT (Maximum Peak Power Tracking)

  • Solar Power Battery Charger

  • 1MHz Frequency Capability
  • 1A Sink/Source Gate Drive
  • Programmable Pulse-by-Pulse Overcurrent Protection
  • Programmable Soft Start

Re-calculate Data

Data is based on the following assumptions.

Note: The temperature and confidence level may be adjusted to your requirements.

Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
