FL7740 SOIC10
CASE 751EE MARKING DIAGRAM Description The FL7740 provides accurate CV regulation in the steady state
with differentiated dynamic function to minimize overshoot and
undershoot of output voltage in line and load transient condition.
Standby power is less than 0.3 W for smart lighting application and
power factor is higher than 0.9 even at half load condition when
enabling PF optimizer for wide output power scalability.
Startup time is less than 0.2 sec with built−in high voltage startup
circuit and output voltage quickly reaches to the target CV level by
loop gain transition technique during startup.
Various protections such as Overload, output diode short, sensing
resistor short, output short and output over voltage protection
guarantee high system reliability. Z = Plant code
