The LZC813 is a single-power stage,
isolated and primary side offline LED lighting
regulator which achieves high power factor.
The proprietary real-current control method
can control the LED current accurately from
the primary side information. It can
significanly simplify the LED lighting system
design by eliminating the secondary side
feedback components and the opto-coupler.
The LZC813 integrates active power factor
correction and works in Quasi Resonance
mode (QRM) in order to reduce the
MOSFET switching losses. With a building in
650V start-up MOSFET, IC can eliminate the
power loss caused by start-up resistors to
provide a high efficiency solution for lighting
applications. The external programmable
line voltage compensation provides a more
precise output current throughout the
universal AC input voltage range. The
leading edge blanking circuit on the CS/FB
input removes the signal glitch and results in
reduced external components and system
cost. The multi-protection features of
LZC813 greatly enhance the system
reliability and safety. The LZC813 features
VDD and output over voltage protection;
output short circuit protection, cycle-by-cycle
current limit and secondary peak current
protection on CS pin, VDD UVLO and
auto-restart and over-temperature protection.
The driver output voltage is clamped at 18V
to protect the external power MOSFET.
