GreenChip drivers for LED lighting
A valley is detected and accepted if both the frequency of the oscillations and the voltage
swing are within the range specified (f ring and ? V vrec(min) ) for detection. If a valid valley is
not detected, the secondary stroke is continued until the maximum off-time (t off(high) ) is
reached, then the next cycle is started.

8.4 Protective features
The IC has the following protective features:

UnderVoltage LockOut (UVLO)
Leading-Edge Blanking (LEB)
OverCurrent Protection (OCP)
Internal OverTemperature Protection (OTP)
Brownout protection
Short-Winding Protection (SWP)
Output Short Protection (OSP)
LED overtemperature control and protection
The SWP and the OSP are latched protections. These protections cause the IC to halt
until a reset (a result of power cycling) is executed. When V CC drops lower than V CC(rst) ,
the IC resets the latch protection mode. The internal OTP and LED over temperature
protections are safe-restart protections. The IC halts, causing V CC to fall lower than
V CC(stop) , and instigates start-up. Switching starts only when no fault condition exists.
