NCP1200
PWM CurrentMode
Controller for LowPower
Universal OffLine Supplies
Housed in SOIC8 or PDIP8 package, the NCP1200 represents a
major leap toward ultracompact Switchmode Power Supplies. Due 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 shortcircuit
protection lets the designer build an extremely lowcost ACDC 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 gatecharge switching devices like
an IGBT or a MOSFET thus requiring a very small operating power.
Due to currentmode control, the NCP1200 drastically simplifies the
design of reliable and cheap offline converters with extremely low
acoustic generation 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 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 selfsupplied from the DC rail, eliminating the
need of an auxiliary winding. This feature ensures operation in
presence of low output voltage or shorts.
