NCP1201
PWM CurrentMode
Controller for Universal
OffLine Supplies Featuring
Low Standby Power with
Fault Protection Modes
Housed in SOIC8 or PDIP8 package, the NCP1201 enhances the
previous NCP1200 series by offering a reduced optocoupler current
with additional Brownout Detection Protection (BOK). Similarly, the
circuit allows the implementation of complete offline ACDC
adapters, battery chargers or Switchmode Power Supplies (SMPS)
where standby power is a key parameter.
The NCP1201 features efficient protection circuitry. When in the
presence of a fault (e.g. failed optocoupler, overcurrent condition, etc.)
the control permanently disables the output pulses to avoid subsequent
damage to the system. The IC only restarts when the user cycles the
mains power supply.
With the low power internal structure, operating at a fixed 60 or
100 kHz, the controller supplies itself from the highvoltage rail,
avoiding the need of an auxiliary winding. This feature naturally eases
the designer’s task in battery charger applications. Finally,
currentmode control provides an excellent audiosusceptibility and
inherent pulsebypulse control.
When the load current falls down to a predefined setpoint (V
SKIP
)
value, e.g. the output power demand diminishes, the IC automatically
enters the skip cycle mode and can provide excellent efficiency under
light load conditions. The skip mode is designed to operate at
relatively lower peak current so that acoustic noise that commonly
takes place will not happen with NCP1201.
