FS8S0765RCB
Fairchild Power Switch (FPS™)
Features
Description
Burst Mode Operation to Reduce the Power
FS8S0765RCB is a Fairchild Power Switch (FPS) that is
specially designed for off-line SMPS of CRT monitors
with minimal external components. This device is a
current mode pulse-width modulated (PWM) controller
combined with a high-voltage power SenseFET in a single
package. The PWM controller features integrated
oscillator to be synchronized with the external sync
signal, under-voltage lockout, optimized gate driver,
temperature compensated precise current sources for
the loop compensation. This device also includes
various fault-protection, circuits such as over voltage
protection, overload protection, abnormal over current
protection and over-temperature protection, Compared
with a discrete MOSFET and PWM controller solution,
FPS can reduce total cost, component count, size, weight,
while increasing efficiency, productivity, and system
reliability. This device is well suited for the cost-effective
monitor power supply.
