  • Output Power: Up to 5 W (depending on configuration)
  • Switching Frequency: 100 kHz (fixed)
  • Maximum Duty Cycle: 80%
  • Start-Up Current: 100 µA (typical)
  • Operating Current: 2.5 mA (typical)
  • Peak Current Limit: 136 mA (fixed)
  • Operating Temperature Range: -40°C to +125°C
  • Package: SOT-223 (4-pin)

Descriptions:

The NCP1052ST136T3G integrates a high-voltage power switch, oscillator, control circuitry, and protection features into a single chip. It is commonly used in flyback and buck converter topologies for offline power supplies, such as adapters, auxiliary power supplies, and standby circuits.

Features:

  • Integrated 700 V Power MOSFET
  • Auto-Restart Protection (for overload and short-circuit conditions)
  • Built-in Soft-Start (reduces inrush current)
  • Frequency Jittering (reduces EMI emissions)
  • Under-Voltage Lockout (UVLO)
  • Thermal Shutdown Protection
  • Low Standby Power Consumption

This device is suitable for cost-effective, space-constrained applications requiring reliable offline power conversion.
