SC4808C

High Performance Dual Ended PWM Controller POWER MANAGEMENT Description The SC4808C is a dual-ended, high frequency, integrated PWM controller, optimized for isolated applications that require minimum space. It can be configured for current or voltage mode operation with required control circuitry where secondary side error amplifier is used. SC4808C Features ‹ ‹ ‹ ‹ ‹ ‹ ‹ ‹ ‹ 120µA starting current Pulse by pulse current limit Programmable operation up to 1MHz Internal soft start Programmable line undervoltage lockout Over current shutdown Dual output drive stages on push-pull configuration Programmable internal slope compensation Programmable mode of operation (peak current mode or voltage mode) External frequency synchronization Bi-phase mode of operation -40 to 105 °C operating temperature MSOP-10 lead free package. This product is fully WEEE and RoHS compliant Telecom equipment and power supplies Networking power supplies Industrial power supplies Push-pull converter Half bridge converter Full bridge converter Isolated VRM’s Some of the key features are high frequency operation of 1 MHz that allows the use of smaller components thus saving cost and valuable board space. An internal ramp www.DataSheet4U.com on the Current Sense pin allows Internal Slope Compensation programmed by an external resistor. Other features include programmable frequency up to 1MHz, ‹ Pulse by Pulse current and Line Monitoring Input with ‹ Hysteresis to reduce stress on the power components. ‹...
