Overview
Data Sheet 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.
· Frequency Fold Back for High Average Effi- About 20kHz frequency switching is able to avoid the ciency audible noise as well as reduce the standby loss.
· Soft Switching for Reducing EMI · Useful Pin Fault Protection: The AP3103 features a lot of functions such as the SENSE Pin Floating Leading-Edge Blanking (LEB) of the current sensing, RI Pin Short to Ground internal slope compensation and several protection RI Pin Floating functions including cycle-by-cycle current limit FB/Opt-coupler Open/short (OCP), VCC Over Voltage Protection (VOVP), OTP, · Comprehensive System Protection Feature: OLP protection.
VCC Over Voltage Protection (VOVP) This IC is available in SOT-23-6 and DIP-8 packages.
Over Temperature Protection (OTP) Over Load Protection (OLP) · Mini Size with Packages Applications · Switching AC-DC Adapter/Charger · ATX/BTX Auxiliary Power · Set-top Box(STB) Power Supply · Open Frame Switching Power Supply Apr.
