Overview

The FSDM0465RE, FSDM0565RE, and FSDM07652RE are an integrated Pulse Width Modulator (PWM) and SenseFET specifically designed for high-performance offline Switch Mode Power Supplies (SMPS) with minimal external components. This device is an integrated high-voltage power-switching regulator that combines an avalanche-rugged SenseFET with a current mode PWM control block. The PWM controller includes an integrated fixed-frequency oscillator, under-voltage lockout, leading-edge blanking (LEB), optimized gate driver, internal soft-start, temperature-compensated precise-current sources for a loop compensation, and self-protection circuitry. Compared with a discrete MOSFET and PWM controller solution, it can reduce total cost; component count, size, and weight; while simultaneously increasing efficiency, productivity, and system reliability. This device is a basic platform well suited for cost-effective designs of flyback converters.

  • Internal Avalanche Rugged Sense FET
  • Advanced Burst-Mode Operation Consumes Under 1 Watt at 240VAC&0.5W Load
  • Precision Fixed Operating Frequency (66kHz)
  • Internal Start-up Circuit
  • Improved Pulse-by-Pulse Current Limiting
  • Over Voltage Protection (OVP)
  • Overload Protection (OLP)
  • Internal Thermal Shutdown Function (TSD)
  • Auto-Restart Mode
  • Under Voltage Lockout (UVLO) with Hysteresis
  • Low Operating Current (2.5mA)
  • Built-in Soft-Start <B>Application</B>
  • SMPS for LCD Monitor and STB
  • Adaptor

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.)
