SSL21081AT
description
The SSL21081AT is a high-voltage Integrated Circuit (IC) for driving LED lamps in general mains non-dimmable lighting applications.
The main benefits are:
- Small Printed-Circuit Board (PCB) footprint; pact solution
- High efficiency (up to 95 %)
- Ease of integration
- Low electronic Bill Of Material (BOM)
The IC incorporates a 300 V MOSFET.
The IC works as boundary conduction mode converters, typically in buck configuration. It has been designed to start up directly from the HV supply by an internal high-voltage current source. Thereafter, the d V/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 m A of supply current with an internal clamp limiting the supply voltage.
The IC provides accurate output current control with LED current accuracy within 5 %. It can be operated using Pulse-Width Modulation (PWM) current regulation. It includes many...
