NCP1230
LowStandby Power High
Performance PWM
Controller
The NCP1230 represents a major leap towards achieving low
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.
The NCP1230 also features an internal latching function that can be
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
CC
to ground. True
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.
