NCP1203
PWM Current-Mode
Controller for Universal
Off-Line Supplies Featuring
Standby and Short Circuit
Protection
Housed in SOIC ? 8 or PDIP ? 8 package, the NCP1203 represents a
http://onsemi.com
major leap toward ultra ? compact Switchmode Power Supplies and
represents an excellent candidate to replace the UC384X devices. Due
to its proprietary SMARTMOS ? Very High Voltage Technology, the
circuit allows the implementation of complete off ? line AC ? DC
adapters, battery charger and a high ? power SMPS with few external
components.
With an internal structure operating at a fixed 40 kHz, 60 kHz or
100 kHz switching frequency, the controller features a high ? voltage

startup FET which ensures a clean and loss ? less startup sequence. Its
current ? mode control naturally provides good audio ? susceptibility
and inherent pulse ? by ? pulse control.
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 improved efficiency at light loads
while offering excellent performance in standby conditions. Because

this occurs at a user adjustable low peak current, no acoustic noise
takes place.
The NCP1203 also includes an efficient protective circuitry which,
in presence of an output over load 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. Finally, a
