NCP4300AVoltage Reference and Dual Operational Amplifier | Linear | 4 | Obsolete | Dual Operational and Voltage The NCP4300A is a monolithic integrated circuit specifically designed to control the output current and voltage levels of switchmode battery chargers and power supplies. This device contains a precision 2.6 V shunt reference and two operational amplifiers.Op-Amp 1 is designed to perform voltage control and has its non-inverting input internally connected to the reference. Op-Amp 2 is designed for current control and has both inputs uncommitted. The NCP4300A offers the power converter designer a control solution that features increased precision with a corresponding reduction in system complexity and cost. This device is available in an 8-lead surface mount package. |
NCP4303Secondary Side Controller, Synchronous Rectification, for High Efficiency SMPS | Power Supply Controllers, Monitors | 1 | Obsolete | The NCP4303A/B is a full featured controller and driver tailored to control synchronous rectifier circuitry in switch mode power supplies. Because of its versatility, it can be used in various topologies such as flyback, forward and half bridge resonant LLC.The combination of externally adjustable minimum on and off times helps to fight the ringing induced by the PCB layout and other parasitic elements. Therefore, a reliable and noise less operation of the SR system is insured.The extremely low turn off delay time, high sink current capability of the driver and automatic package parasitic inductance compensation system allow to maximize synchronous rectification MOSFET conduction time that enables further increase of SMPS efficiency.Finally, a wide operating VCCrange combined with two versions of driver voltage clamp eases implementation of the SR system in 24 V output applications.NCP4304 is recommended for new designs. NCP4303 will continue to be supported in production. NCP4304 was introduced to enhance the performance of LLC designs which use the Trigger input. Other performance and applications are the same. |
