MARKING

Housed in SO–8 or DIP8 package, the NCP1200 represents a major

leap toward ultra–compact Switch–Mode Power Supplies. Thanks to a

novel concept, the circuit allows the implementation of a complete

offline battery charger or a standby SMPS with few external

components. Furthermore, an integrated output short–circuit

protection lets the designer build an extremely low–cost AC/DC wall

adapter associated with a simplified feedback scheme.

With an internal structure operating at a fixed 40 kHz, 60 kHz or 100

kHz, the controller drives low gate–charge switching devices like an

IGBT or a MOSFET thus requiring a very small operating power.

Thanks to current–mode control, the NCP1200 drastically simplifies

the design of reliable and cheap offline converters with excellent

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 excellent efficiency at light loads.

Because this occurs at low peak current, no acoustic noise takes place.

Finally, the IC is self–supplied from the DC rail, eliminating the

need of an auxiliary winding. This feature ensures operation in

presence of low output voltage or shorts.
