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.

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit
values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied,
damage may occur and reliability may be affected.
