NCP1230

Low-Standby 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 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.
