1 Secondary Side Synchronous Rectifier ontroller Features High speed secondary synchronous rectifier High system efficiency from no load to full load Light load protection function DM topology 200 high voltage technology Ultra low startup and quiescent current cc ranges from 11.6 to 19.5 SOP-8 green (Halogen free) package Description GR8387 is the synchronous rectifier controller used in discontinuous conduction mode and quasi-resonant flyback converters. The I controls N-MOSFET to substitute Schottky diode. The D to S voltage difference is sensed to decide the polarity of the current and turn the power switch on/off in nearly of zero current transition. When light load the gate driver output can be disable to avoid long MOSFET turn on period.

7 Application Information Overview GR8387, the secondary side driver I, emulates the operation of diode rectifier by driving a synchronous rectifier MOSFET. Using low R DS_ON N-MOSFET to substitute Schottky diode, the lower turn-on voltage will reduce conduction loss on rectifier. The efficiency of power converter will be boosted. Under-oltage Lockout (ULO) The GR8387 remains off until voltage exceeds turn-on threshold voltage (_ON). As the I is off, it takes as little current as 75uA. Once the rises above _ON, the I starts to work. It continues to operate until the voltage drops below turn-off threshold voltage (_OFF). makes OUT pin be pulled low and turns the MOSFET off. Minimum On time (MOT) and Turn Off Latch To avoid the mistrigger which is caused by noise as MOSFET is switching, minimum on time (MOT) function and turn off latch control have been built in GR8387. When OUT pin is pulled high, the minimum on time (MOT) which is setting by the resistor between MOT pin to ground keeps the MOSFET on. As OUT pin is pulled low, the MOSFET won t open again until the DS over reset threshold oltage (TH3), which means that the secondary side discharge has finished. Sleeping / Normal Mode Since the GR8387 cc pin voltage exceeds _ON, there are two modes available, sleeping mode and normal mode. The I will be in sleeping mode as EN pin is pulled low. In this mode, the I draws a very low quiescent supply current and MOSFET goes into off state. As EN pin is pulled high, the I will be in normal mode. In this mode, MOSFET starts to switch, and the I needs higher supply current to support function blocks working. OUT Pin Turn on/off Phase As secondary side rectifier is in conduction state, (Fig.1, T2) the rectifier current flows through the body diode of the MOSFET at first, which will generate a negative DS voltage on the MOSFET. The negative voltage will be below turn-on threshold voltage (TH2), and then the GR8387 OUT will be pulled high to drive the MOSFET turn on. The current will flow through the channel of the MOSFET and causes the DS voltage to drop down. When the MOSFET is turned on, it stays on until the rectifier current reduces to the level while DS exceeds the turn-off threshold voltage (TH1). This er opyright Grenergy OPTO, Inc. 7
