1 / 1 page  MT79325 Maximizing IC Performance Single Stage, Low THD, AC-DC LED Driver Email: sales@maxictech.com www.maxictech.com Rev. 1.05 Tel: 86-10-62662828 Copyright © 2016 Maxic Technology Corporation Page 1 DESCRIPTION The MT79325 is a single-stage, primary side control AC-DC LED driver with active power factor correction. The MT79325 integrates on-chip PFC circuit operates in discontinuous conduction mode (DCM) to achieve high power factor and low harmonic distortion (THD). With MAXIC Proprietary control technique, precision LED current is achieved without secondary side sense and feedback circuit including opto-coupler. Embedded with 700V power MOSFET, the peripheral circuit is simplified. The MT79325 provides various protections, such as over current protection (OCP), over voltage protection (OVP), short circuit protection (SCP) and over temperature protection (OTP), etc, to improve system reliability. FEATURES Single-stage Active PFC for high power factor and low THD (<8%) Primary side control eliminates opto-coupler High precision LED current (±3%) Cycle-by-cycle current limiting Under-voltage lockout (UVLO) protection VDD and output over voltage protection Adjustable constant current and output power setting Power on soft-start Embedded with 700V power MOSFET Available in DIP8 package APPLICATIONS AC/DC LED driver applications Signal and decorative LED lighting E27/PAR30/PAR38/GU10 LED lamp T8/T10 LED String Typical Application Circuit |
