CM6900

CM6900 Resonant Controller GENERAL DESCRIPTION FEATURES CM6900 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 accomplished 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 Comparator. 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 CM6900 Pin Configuration ORDERING INFORMATION Part Number CM6900GIS* CM6900GIP* CM6900XIS* CM6900XISTR* CM6900XIP* Temperature Range -40℃ to 125℃ -40℃ to 125℃ -40℃ to 125℃ -40℃ to 125℃ -40℃ to 125℃ *Note : G : Suffix for Pb Free Product X : Suffix for Halogen Free Product TR : Package is Typing Reel 2010/03/10 Rev1.1 Champion Microelectronic Corporation Package 16-Pin SOP (S16) 16-Pin PDIP (P16) 16-Pin SOP (S16) 16-Pin SOP (S16) 16-Pin PDIP (P16) Page 1 CM6900 Resonant Controller TYPICAL APPLCATION CIRCUIT +VD C DRVH DRVHGND C32 47nF/630V DRVL IPLIMIT C42 470nF/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 10...
