SSL3401HN
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 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:
- Over Voltage Protection (OVP)
- Coil Current Limitation (CCL)
- Short LED protection (SLED)
- Open LED protection (OLED)
- Under Voltage Lock Out (UVLO)
- Advanced adaptive Over Temperature Protection (OTP)
