1. General Description

The TCIL6568 is a non-isolated BUCK topology constant current control LED

controller with Active Power Factor Correction (APFC). For 85Vac-265Vac input voltage, it

can achieve high precision LED output current, high power factor, low THD and high system

efficiency.

The TCIL6568 works in boundary conduction mode to reduce the MOSFET switching

losses. The TCIL6568 integrate 600V MOSFET internally, which simplifies external circuit.

The system full wave detection mode makes the high precision of constant current controlling,

also the Line Voltage Regulation and Load Regulation.

The multi-protection feature of TCIL6568 significantly improves the system reliability

and safety. The TCIL6568 features VCC under voltage lock out, LED open/short-circuit

protection, CS resistor open-circuit protection, cycle-by-cycle current limit, and intelligent

thermal adjust.

TCIL6568-7 is for 3 to 7 watt driver applications and TCIL6568-14 is for 9-14 watt

driver applications.
