CM6900G Datasheet | Champion Microelectronic

DESCRIPTION FEATURES CM6900G is resonant controller tailor for series z topology with synchronous operation to achieve z high efficiency to meet today’s power need. It is used for DC-DC conversion in the offline z application. Light load regulation is acplished z by transitioning the controller from frequency z modulation mode into PWM mode. z z Supply Voltage Range : 10V to 15V. Typical Peak Drive from 12V supply : (PMOS~200 ohm and NMOS~100 ohm). UVLO=13V with 3V Hystetesis. Reference OK parator. FM/PWM Mode Operation. Softstart Capability with Shutdown Function. Latch or Auto-Restart during Current Limit or OVP. APPLICATIONS z DC-DC Power Supply. z LED Lighting Power Supply z Server Power z Industrial Power Supply z High Power Adaptor CM6900G Pin Configuration ORDERING INFORMATION Part Number CM6900GIS - Note: G : Suffix for Pb Free Product Temperature Range -40℃ to 125℃ Package 16-Pin SOIC (S016) 2007/11/22 Rev1.0 Champion Microelectronic Corporation Page 1 Resonant Controller TYPICAL APPLCATION CIRCUIT +VD C DRVH DRVHGND C32 47n F/630V DRVL IPLIMIT C42 470n F/25V D12 R50 330Ω 1/4W BAV99 D13 BAV99 D10 SCD14 R43 10Ω D11 SCD14 R46 10Ω Q12 CMT08N50 H S2 HS R44 47KΩ C30 100p F/1KV L4 200uh/RM8 Q14 CMT08N50 R49 47KΩ C37 100p F/1KV 11 22 11...
