Description
- The NCP4304ADR2G is a secondary side synchronous Rectification Driver for use with high efficiency SMPS topologies. The full featured controller and driver tailored to control synchronous rectification circuitry in switch mode power supplies. Due to 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 VCC range combined with two versions of driver voltage clamp eases implementation of the SR system in 24V output applications.
- Self-contained control of synchronous rectifier in CCM, DCM and QR Flyback applications
- Precise true secondary zero current detection with adjustable threshold
- Automatic parasitic inductance compensation input
- Typically 40ns turn off delay from current sense input to driver
- Zero current detection pin capability up to 200V
- Disable input to enter standby or low consumption mode
- Adjustable minimum on time independent of VCC level
- Adjustable minimum off time independent of VCC level
- Low start-up and standby current consumption
- Maximum frequency of operation up to 500kHz
- Allows for proper timing of SR MOSFET turn on and turn off
- Maximizes conduction time of the MOSFET to increase efficiency
- Improves performance for applications working in deep CCM
- Enters the IC into a low consumption standby mode
- Prevents accidental MOSFET turn on or turn off due to ringing
- Fast turn off of MOSFET for optimized conduction period
- Allows for direct supply from the power supply output voltage in a wide range of applications
