PWM CurrentMode
Controller for Universal
OffLine Supplies Featuring
Low Standby Power
Housed in SOIC8 or PDIP8 package, the NCP1200A enhances
the previous NCP1200 series by offering a reduced optocoupler
current together with an increased drive capability. Due to its novel
concept, the circuit allows the implementation of complete offline
ACDC adapters, battery charger or a SMPS where standby power is a
key parameter.
With an internal structure operating at a fixed 40 kHz, 60 kHz or
100 kHz, the controller supplies itself from the highvoltage rail,
avoiding the need of an auxiliary winding. This feature naturally eases
the designer task in battery charger applications. Finally,
currentmode control provides an excellent audiosusceptibility and
inherent pulsebypulse control.
When the current setpoint falls below a given value, e.g. the output
power demand diminishes, the IC automatically enters the socalled
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.
The NCP1200A 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 autorecovers.
