VERSATILE COST EFFECTIVE GREEN PWM CONTROLLER
General Description
Features
AP3103
The AP3103 is a low startup current, current mode · Bi-CMOS Process with Excellent Performance
PWM controller with green-mode power-saving operation. The PWM switching frequency at normal operation is externally programmable and is trimmed to a tight range. The dithering of frequency will improve
· · ·
Very Low Start-up Current:(< 15µA) Current Mode Control Non-audible-noise Green-mode Control
EMI feature. When the load decreases, the frequency · LEB (Leading-edge Blanking) on SENSE Pin
will reduce and when at a very low load, the IC will · Internal Slope Compensation
enter the ‘skip mode’ to minimize switching loss.
