onsemi DAP011B
The DAP011A/B/D 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. The DAP011A/B/D is a current mode controller with internal ramp compensation. The DAP011A/B/D itself goes into cycle skipping at light loads while limiting peak current (to 25% of nominal peak) so that no acoustic noise is generated.| Part No. | DAP011B |
