Overview

The FSL137MRIN is an integrated Pulse Width Modulation (PWM) controller and SenseFET specifically designed for offline Switched Mode Power Supplies (SMPS) with minimal external components. The PWM controller includes an integrated fixed-frequency oscillator, Line Over-Voltage Protection (LOVP), Under-Voltage Lockout (UVLO), Leading-Edge Blanking (LEB), optimized gate driver, internal soft-start, temperature-compensated precise current sources for loop compensation, and self-protection circuitry.
Compared with a discrete MOSFET and PWM controller solution, the FSL137MRIN reduces total cost, component count, size, and weight; while simultaneously increasing efficiency, productivity, and system reliability. This device provides a basic platform suited for cost-effective design of flyback converters.

  • This product is general usage and suitable for many different applications.

  • Advanced Soft Burst Mode for Low Standby Power and Low Audible Noise
  • Random Frequency Fluctuation (RFF) for Low EMI
  • Under 50 mW Standby Power Consumption at 265 VAC, No-load Condition with Burst Mode
  • Pulse-by-Pulse Current Limit
  • Overload Protection (OLP), Over-Voltage Protection (OVP), Abnormal Over-Current Protection (AOCP), Internal Thermal Shutdown (TSD) with Hysteresis, Output-Short Protection (OSP), and Under-Voltage Lockout (UVLO) with Hysteresis, Line Over-Voltage Protection (LOVP)
  • Low Operating Current (0.4 mA) in Burst Mode
  • Internal Startup Circuit
  • Internal High-Voltage SenseFET: 700 V
  • Built-in Soft-Start: 15 ms
  • Auto-Restart Mode

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.)
