MT9713D is a high precision LED constant current driver IC with full range analog dimming, which is applied to non-isolated buck topology. Without any peripheral RC components, directly input PWM dimmable signal into MT9713D to realize no flicker analog dimming.
With MAXIC proprietary technology, MT9713D has good dimming consistency. And the moisture-proof OVP can be realized to the full range of dimming.
The typical standby current is 120uA, which can achieve low power consumption.
MT9713D is suitable for full range input voltage (85Vac~265Vac) applications with excellent line regulation and load regulation. MT9713D integrates high precision current sensing circuit, which is ideal for high precision LED constant current output and high frequency operation.
With the embedded high voltage startup circuit and integrated 500V power MOSFET, VCC capacitor and startup resistor are not needed. The peripheral circuit is extremely simplified, and the BOM cost is reduced accordingly.
MT9713D supports various protections, such as moisture-proof OVP, thermal regulation, output short circuit protection, etc., to improve system reliability.
