SSL21084T
Mains dimmable LED driver IC
2. Features and benefits
LED driver IC for driving strings of LEDs or high-voltage LED modules from a rectified
mains supply
Power-efficient boundary conduction mode operation with:
No reverse recovery losses in freewheel diode
Zero-Current Switching (ZCS) for switch turn-on
Zero-voltage or valley switching for switch turn-off
Minimal required inductance value and size
Fast transient response through cycle-by-cycle current control:
No overshoot or undershoot in the LED current
Simple high input power factor solution (>0.9)
Internal Protection features:
UnderVoltage LockOut (UVLO)
Leading-Edge Blanking (LEB)
OverCurrent Protection (OCP)
Short-winding protection (SWP)
Internal OverTemperature Protection (OTP)
Brownout protection
Output Short Protection (OSP)
Mains phase cut dimmable LED driver solution:
Supports both leading-edge and trailing-edge dimmers
Easy external temperature protection with a single NTC
Open output protection using external components
Compatible with wall switches with built-in indication light during standby
IC lifetime easily matches or surpasses LED lamp lifetime
Input current distributed evenly over the phase, reducing required output capacitor
size and bleeder dissipation
3. Applications
The SSL21084T are intended for mains dimmable compact LED lamps for single mains
input voltages. Mains input voltages include 100 V (AC), 120 V (AC) and 230 V (AC).
