SSL21081/SSL21083
Compact non-dimmable LED driver IC
Rev. 5 — 11 October 2012
Product data sheet
1. General description
The SSL21081/SSL21083 are a range of high-voltage Integrated Circuits (ICs) for driving
LED lamps in general mains non-dimmable lighting applications.
The main benefits of these products are:
• Small Printed-Circuit Board (PCB) footprint, and compact solution
• High efficiency (up to 95 %)
• Ease of integration
• Low electronic Bill Of Material (BOM)
These ICs incorporate a 300 V or 600 V MOSFET.
The ICs work as boundary conduction mode converters, typically in buck configuration.
The IC range has been designed to start up directly from the HV supply by an internal
high-voltage current source. Thereafter, the dV/dt supply is used with capacitive coupling
from the drain, or any other auxiliary supply. This function provides full flexibility in the
application design. The IC consumes 1.3 mA of supply current with an internal clamp
limiting the supply voltage.
The ICs provide accurate output current control with LED current accuracy within 5 %.
The ICs can be operated using Pulse-Width Modulation (PWM) current regulation and has
many protection features including easy LED temperature feedback.

8.8 Heat sink
The copper of the PCB acts as the heat sink for SSL21081/SSL21083 applications.
Equation 1 shows the relation between the maximum allowable power dissipation P and
the thermal resistance from junction to ambient.
Rthj – a = Tjmax – Tamb P
(1)
Where:
Rth(j-a) = thermal resistance from junction to ambient
Tj(max) = maximum junction temperature
Tamb = ambient temperature
P = power dissipation
