SSL2108X
Drivers for LED lighting
No binning on LED forward voltage required
Internal Protections:
UnderVoltage LockOut (UVLO)
Leading-Edge Blanking (LEB)
OverCurrent Protection (OCP)
Short-Winding Protection (SWP)
Internal OverTemperature Protection (OTP)
Brownout protection
Output Short Protection (OSP)
Low component count (see Figure 4) LED driver solution:
No Schottky diode required due to ZCS
No dim switch and high-side driver required for PWM dimming
Easy external temperature protection without additional components
Option for soft-start function
Hotaru switch compatible during standby1
IC lifetime easily matches or surpasses LED lamp lifetime
3. Applications
SSL2108X products are intended for compact LED lamp ballasts with accurate fixed
current output for single mains input voltages. Mains input voltages include 100 V,
120 V and 230 V (AC). The output signal can be modulated using a PWM signal.
