SCM1101A Highly integrated PWM controller Features            Packaging Soft-Start Function, Externally Programmable Extremely Low Start-up current of 1uA typical Frequency Reduction at Light Load and Burst Mode Control under no load Programmable Maximum Switching Frequency,up to 480KHz Built-in Slope Compensation and Feed-forward Compensation Circuit Cycle-by-Cycle Current Limiting RI Pin Short-circuit Protection VDD Over-Voltage Protection (OVP) and Under-Voltage Lockout (UVLO) Built-in (over-current protection)OCP time Feedback Open-loop Protection/Short-circuit Protection VIN Under-Voltage Protection Mechanical package: MSOP-8 (see “Ordering information” for details of silk screen). Applications    DC-DC Isolate Power Supplies Instrument Power Supplies Isolated Telecom Converter Description This highly integrated SCM1101A current mode PWM controller is ideal for Isolate DC-DC converter applications. The PWM switching frequency is internally adjusted within a tight range. The chip’s maximum working frequency can be changed by means of external resistors. To conserve energy under light load conditions, the green mode function continuously decreases the switching frequency, thus enabling the converter to maintain high efficiency over the entire load range. For optimized standby power consumption, the power supply enters into a burst mode under no load conditions. The SCM1101A design also integrates a series of protection features that will enhance the power system’s reliability. These functions include VIN Under-Voltage Protection, VDD Under-Voltage Lock Out (UVLO), VDD Over-Voltage Protection, Soft-Start pin SS Suspended Protection, Feedback Open-Loop Protection / Short-Circuit and Overload Protection and CS pin Suspended Protection. Simplified Schematic Function Curves NOTE: Vin=18~75V,Vout=15V,Pout=10W.
