DAP011/DAP011C
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.
When the current setpoint falls below a given value, e.g. the
output power demand diminishes, the IC automatically enters
the so−called skip cycle mode and provides excellent
efficiency at light loads. Because this occurs at a user
adjustable low peak current, no acoustic noise takes place. Due
to a proprietary SoftSkip technique, the absence of sharp
transitions during skip mode significantly reduces acoustical
noise.
The DAP011/DAP011C features an efficient protective
circuitry which, in presence of an overcurrent condition,
disables the output pulses while the device enters a safe burst
mode, trying to restart. Once the default has gone, the device
auto−recovers. By implementing a timer to acknowledge a
fault condition, independently from the auxiliary supply, the
designer’s task is eased when stringent fault mode
conditions need to be met.
A dedicated input helps triggering a latch−off circuitry
which permanently disables output pulses.
