30D16

Product Summary

The 30D16 is a Low-Standby Power High Performance PWM Controller. The 30D16 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, the 30D16 contains all needed control functionality to build a rugged and efficient power supply. The 30D16 is a current mode controller with internal ramp compensation. Among the unique features offered by the 30D16 is an event management scheme that can disable the front-end PFC circuit during standby, thus reducing the no load power consumption. The 30D16 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 30D16 has a high-voltage startup circuit that eliminates external components and reduces power consumption.
