Low-Standby Power High

Controller
standby power in medium−to−high power Switched−Mode Power
Supplies such as notebook adapters, off−line battery chargers and
consumer electronics equipment. Housed in a compact 8−pin package
(SOIC−8, SOIC−7, or PDIP−7), the NCP1230 contains all needed
control functionality to build a rugged and efficient power supply. The
NCP1230 is a current mode controller with internal ramp
compensation. Among the unique features offered by the NCP1230 is
an event management scheme that can disable the front−end PFC
circuit during standby, thus reducing the no load power consumption.
The NCP1230 itself goes into cycle skipping at light loads while
limiting peak current (to 25% of nominal peak) so that no acoustic
noise is generated. The NCP1230 has a high−voltage startup circuit
that eliminates external components and reduces power consumption.
used for OVP protection. This latch is triggered by pulling the CS pin
above 3.0 V and can only be reset by pulling V
overload protection, internal 2.5 ms soft−start, internal leading edge
blanking, internal frequency dithering for low EMI are some of the
other important features offered by the NCP1230.
