SSL3401HN

Low voltage dimmable controller for LED lighting

Rev. 2 — 28 January 2014

Product data sheet

1. General description

The SSL3401HN is a Switched Mode Power Supply (SMPS) controller IC. It operates in

combination with a phase cut dimmer and a 12 V (AC or DC) low voltage electronic or

magnetic transformer. It is designed to drive LED devices and include a dimmer

conduction phase detector.

The chip includes a hysteretic controller for the power converter. It is most suitable for use

with a linear LED current source. Two embedded Proportional-Integral (PI) controllers and

a 0.052 % resolution PWM generator, adjusted by the dimmer conduction phase, ensure

excellent LED current stability for a dimming range from 100 % to less than 5 %. It also

minimizes the power loss across the LED current source.

Several protection mechanisms are available:

• OverVoltage Protection (OVP)

• Coil Current Limitation (CCL)

• Short LED protection (SLED)

• Open LED protection (OLED)

• UnderVoltage LockOut (UVLO)

• Advanced adaptive OverTemperature Protection (OTP)

2. Features and benefits

 Easy migration to existing lighting control infrastructure

 Support most available dimming and low-voltage transformation solutions

 Excellent stability of LED current

 Double PI controllers to enhance the line regulation of the LED current

 Optimized dimming curve for low-voltage transformer compatibility

 Automatic supply frequency detection for seamless operation with 50 Hz, 60 Hz or DC

sources

 Dimmer conduction angle detection

 Coil current limitation

 Temperature roll-back protection

 OverVoltage Protection

 Power-On-Reset (POR)

 Shorted LED protection

 Open LED detection
