Single Chip 700V SenseFET Power Switch
Precision Fixed Operating Frequency: 130kHz
No-load consumption 250mW at 265V AC with
Burst Mode and Down to 60mW with External Bias
Internal Startup Switch
Soft-Start Time Tuned by External Capacitor
Under-Voltage Lockout (UVLO) with Hysteresis
Pulse-by-Pulse Current Limit
Overload Protection (OLP) and Internal Thermal
Shutdown Function (TSD) with Hysteresis
Auto-Restart Mode
No Need for Auxiliary Bias Winding
The FSQ500L is specially designed for a replacement of
linear power supplies with low cost. This device
combines current-mode Pulse Width Modulator (PWM)
with a senseFET. The integrated PWM controller
features include: a fixed oscillator, Under Voltage
Lockout (UVLO) protection, Overload Protection (OLP),
Leading-Edge Blanking (LEB), an optimized gate turn-
on/turn-off driver, Thermal Shutdown (TSD) protection
with hysteresis, and temperature-compensated
precision-current sources for loop compensation. When
compared to a linear power supply, the FSQ500L device
reduces total size and weight, while increasing
efficiency, productivity, and system reliability. This
device provides a basic platform for cost-effective
flyback converters.
