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