FS6X1220-Fairchild Power Switch (FPS)
Description The FS6X1220R is designed for off-line Tesi digitizers with minimal external components. This device is a current mode PWM controller with a high value SenseFET combined with a voltage supply in one package. The PWM controller includes an integrated fixed frequency oscillator, line undervoltage lockout, sleep/shutdown function, thermal shutdown protection, overvoltage protection, pulsed pulse current limit and temperature compensated precision current source primary loop compensation. Compared to discrete MOSFET and PWM controller solutions, the FS6X1220R can reduce overall cost, component count, size and weight while increasing efficiency, productivity and system reliability. This device is ideal for DC-to-DC converter output power applications up to 40W.
Features • Fixed operating frequency for current mode PWM control (at 300kHz)
• Pulse pulse current limit • Overload protection • Over voltage protection • Thermal shutdown • Built-in auto-restart circuit • Input voltage detection and sleep/shutdown function • Internal high-voltage value SenseFET (QFET)
• Supports forwarding or flyback topologies
Applications • DC-DC conversion
