• Manufacturer Part Number: FA5590
• Description: FUJI Power Supply Control IC
• Manufacturer: FUJI [Fuji Electric]

4. Type of FA5590/91
AN-016E Rev.1.2
April-2011
1. Description
power consumption by using high voltage CMOS process. It is equipped with many fault protection functions such
as FB short-circuit detection circuit which stops the operation when abnormal output voltage is detected.
2. Features
 Very Low Standby Power by disusing Input Voltage Detection Resistors
 High-precision over current protection：0.6V±5%
 Improved power efficiency at light load due to Maximum Frequency Limitation
 No Audible Noise at Startup
 Low current consumption by CMOS process
 Enabled to drive power MOSFET directly
 Open/short protection at feedback (FB) pin
 Under-voltage Lockout
 Overvoltage protection
 Restart timer
 Standby function
 8-pin package (SOP)
