Introduction

The LC5500 series is the power IC for the isolated type

LED driver which has an incorporated power MOSFET,

designed for input capacitorless applications, and making it

possible for systems to comply with the harmonics standard

(IEC61000-3-2 class C). The controller adapts the average

current control method for realizing high power factors, and

the quasi-resonant topology contributes to high efficiency

and low EMI noise. The series is housed in either DIP8 or

TO-220F-7L packages, depending on output power

capability. The rich set of protection features helps to real-

ize low component counts, and high performance-to-cost

power supply.

Features and Benefits

• DIP8 package (LC551xD/LC552xD) and TO-220F-7L

package (LC552xF)

• Integrated on-width 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 the startup

performance, suppresses VCC voltage droop during

operation, allows reduction of VCC capacitor value as well

as use of a ceramic capacitor)

• Integrated Leading Edge Blanking (LEB) circuit

• Integrated maximum on-width limit circuit

Off-Line Switching Regulators

Figure 1. The LC5500 series packages for lower wattage versions

are fully molded DIP8s, with pin 7 removed for greater isolation. For

higher wattages, the TO-220F-7L fully molded package is provided,

with three leadform options, all which provide a separation between

pins 1 and 2.

• Dual-chip structure, with an avalanche-guaranteed power

MOSFET (allows simplified surge suppressing circuits)

• Protection features:

▫ Overcurrent protection (OCP): pulse-by-pulse

▫ Overvoltage protection (OVP): auto restart, OVP-

activating pins vary by product series:

*Based on the thermal rating; the allowable maximum output power can be up to

120% to 140% of this value. However, maximum output power may be limited in an

applications with low output voltage or short duty cycle.
