SSL21081AT

Compact non-dimmable LED driver IC

 Internal protections:

 UnderVoltage LockOut (UVLO)

 Leading-Edge Blanking (LEB)

 OverCurrent Protection (OCP)

 Internal OverTemperature Protection (OTP)

 Brownout protection

 Output Short Protection (OSP)

 Low component count LED driver solution (see Figure 3):

 No Schottky diode required due to ZCS

 Easy external temperature protection with a single NTC resistor

 Option for soft-start function

 Compatible with wall switches with built-in indication light during standby1

 IC lifetime easily matches or surpasses LED lamp lifetime

Applications

The SSL21081AT is intended for compact mains non-dimmable LED lighting applications

with accurate fixed current output for single mains input voltages. Mains input voltages

include 100 V (AC), 120 V (AC). The output signal can be modulated using a PWM signal.

The Hotaru switch is a well-known wall switch with built-in light
