Overview

The advanced PWM controller, FAN501A, simplifies isolated power supply design that requires CC regulation of the output. The output current is precisely estimated with only the information in the primary side of the transformer and controlled with an internal compensation circuit, removing the output current-sensing loss and eliminating external CC control circuitry. With an extremely low operating current (250 µA), Burst Mode maximizes light-load efficiency, allowing conformance to worldwide Standby Mode efficiency guidelines.
Compared with a conventional approach using external control circuit in the secondary side for CC regulation, the FAN501A can reduce total cost, component count, size, and weight; while increasing efficiency, productivity, and system reliability.

  • WSaver® Technology Provides Ultra-Low Standby Power Consumption for Energy Star’s 5-Star Level (<30 mW)
  • Constant-Current (CC) Control without Secondary-Side Feedback Circuitry for Discontinuous Conduction Mode (DCM) and Continuous Conduction Mode (CCM)
  • Dual-Frequency Function Changes Switching Frequency (140 kHz / 85 kHz) According to Input Voltage to Maximize Transformer Utilization and Improve Efficiency
  • High Power Density and High Conversion Efficiency in CCM Compact Charger Applications
  • Frequency Hopping to Reduce EMI Noise
  • High-Voltage Startup
  • Precise Maximum Output Power Limit by CC Regulation through External Resistor Adjustment
  • Peak-Current-Mode Control with Slope Compensation to Avoid Sub-Harmonic Oscillation
  • Programmable Over-Temperature Protection with Latch Mode through External NTC Resistor
  • Two-Level UVLO Reduces Input Power in Output Short Situation
  • VS Over-Voltage Protection with Latch Mode
  • VDD Over-Voltage Protection with Auto Restart
  • Available in MLP 4 X 3 Package

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.)
