DAP011 DAP011DR2 SOP-14

DAP011 LCD power supply--PJDZ

PWM Current−Mode
Controller for High−Power
Universal Off−Line Supplies

Housed in an SO−14 package, the DAP011/DAP011C
represents an enhanced version of the Maximus, DAP008,

controller. Due to its high drive capability, SpeedKing drives
large gate−charge MOSFETs which, together with internal
ramp compensation and a user selectable frequency
jittering, ease the design of modern AC/DC adapters.
With an internal structure operating at a fixed 65/100 kHz
frequency, the controller directly connects to the
high−voltage rail for a loss less and clean startup sequence.
Current−mode control also provides an excellent input
audio−susceptibility and inherent pulse−by−pulse control.
Internal ramp compensation easily prevents subharmonic
oscillations from taking place in continuous conduction
mode designs
