Introduction

MT9712BS is a full-range analog dimming, non-isolated buck LED constant-current driver IC. The PWM dimming signal is fed directly into the chip without any additional RC components, enabling flicker-free analog dimming with excellent dimming consistency. OVP with moisture protection is maintained throughout the entire dimming range.

The typical standby current of MT9712BS is 100uA, enabling low-power design.

MT9712BS offers excellent line regulation and load regulation, suitable for applications with a wide input voltage range of 85Vac~265Vac.

MT9712BS integrates a high-precision current sensing circuit for high-accuracy LED constant-current output, with support for high-frequency applications.

MT9712BS integrates a high-voltage startup circuit and a 500V power MOSFET, eliminating the need for a VCC capacitor and startup resistor. This simplifies the peripheral circuitry and significantly reduces system cost.

MT9712BS incorporates multiple protection features, including moisture-resistant adjustable OVP, over-temperature regulation, and output short-circuit protection, enhancing product reliability.
