SSL5001T

Compact non-dimmable LED controller IC

Rev. 2 — 26 June 2014

Product data sheet

1. General description

The SSL5001T is an Integrated Circuit (IC) for driving LED lamps in general lighting

applications. It operates in fixed frequency mode. Frequency jitter is implemented to

reduce ElectroMagnetic Interference (EMI).

The main benefits of this IC include:

• Constant power mode applications support

• Small Printed-Circuit Board (PCB) footprint and compact solution

• High efficiency (85 % typical)

• Ease of integration and many protection features

• Low electronic Bill Of Material (BOM)

• Constant current and constant voltage operation possible using an optocoupler

The VINSENSE and PROTECT pins are reserved for protection purposes. Input

UnderVoltage Protection (UVP), input OverVoltage Protection (OVP), output OVP and

output OverTemperature Protection (OTP) can be implemented using a minimum of

external components.

The IC provides output power control to 10 % LED current accuracy. The IC has many

protection features including easy LED temperature feedback with an external PTC.

Remark: All values are typical values unless otherwise stated

2. Features and benefits

 LED controller IC for driving strings of LEDs or high-voltage LED modules from a

rectified mains supply

 Part of a high-efficiency switch mode flyback or buck/boost product family.

 Controller-only which can drive an external MOSFET

 Very low supply current during start-up and restart (10 A)

 Low supply current during normal operation (0.5 mA without load)

 Applicable in buck/boost and flyback topologies

 Fast transient response through cycle-by-cycle current control:

 Low AC mains ripple in LED current

 No over or undershoots in the LED current

 Internal protection and features:

 UnderVoltage LockOut (UVLO)

 Leading Edge Blanking (LEB)

 General purpose protection input
