LC5560LD
LC5560LD Series
Single-Stage Power Factor Corrected
Off-Line Switching Regulator ICs
Features and Benefits
• Integrated on-time control circuit (it realizes high power
factor by average current control)
• Integrated startup circuit (no external startup
circuit necessary)
• Integrated soft-start circuit (reduces power stress during
start-up on the incorporated power MOSFET and output
rectifier)
• Integrated bias assist circuit (improves startup
performance, suppresses VCC voltage droop during
operation, and allows use of low-rated ceramic capacitor
on VCC pin)
• Integrated Leading Edge Blanking (LEB) circuit
• Integrated maximum on-time limit circuit
• Protection features:
Overcurrent protection (OCP): pulse-by-pulse
Overvoltage protection (OVP): latched shutdown
Overload protection (OLP): latched shutdown
Thermal shutdown (TSD): latched shutdown
Package: 8-pin DIP

Description
The LC5560LD series is the power IC for the non-iso-
lated type LED driver which has an incorporated power
MOSFET, designed for input capacitorless applications, and
making it possible for systems to comply with the harmon-
ics standard (IEC61000-3-2 class C), even during light load
condition.
The controller adapts the average current control method for
realizing high power factors, and the quasi-resonant topol-
ogy contributes to high efficiency and low EMI noise. The
series is housed in DIP8 packages.
The rich set of protection features helps to realize low com-
ponent counts, and high performance-to-cost power supply.
The incorporated MOSFET has a VDSS(min) rating of
650 V. The RDS(on)(max) is 1.9 Ω (LC5566LD) to 3.95 Ω
(LC5565LD). It is capable of a maximum output power of
20 W on 230 VAC supply to 16 W on universal input supply
(85 to 265VAC) (LC5566LD) based on the thermal rating.
Note that the maximum output power can be up to 120% to
140% of this value. However, it may be limited in applica-
tions with low output voltage or short duty cycle. The PWM
oscillation frequency ranges from 60 kHz (LC5566LD) to
72 kHz (LC5565LD).
