ON Semiconductor NCP4306 Operation & User’s Manual

November, 2017 − Rev. 0 1 Publication Order Number: EVBUM2520/D EVBUM2520/D NCP4306 Synchronous Rectification Evaluation Board User's�Manual Description This evaluation board user’s manual describes a high efficiency synchronous rectification evaluation board that can easily replace a secondary side ...

a) b) The evaluation board can be connected in circuit where the rectification diode is in the positive or negative branch. When connection to a positive branch is used, it is necessary to use an external power supply (or auxiliary winding with rectification) to provi ...

Figure 3. Schematic of the NCP4306 The evaluation board was designed to support a minimal external component count implementation. C1 is decoupling capacitor that should be placed as close as possible to the VCC and GND pins. Resistors RMIN_TON and RMIN_TOFF are used to set the protection interval when ...

copper cladding. All components are surface mount. Critical component such as blocking capacitor C1 has to be placed carefully near the IC. The synchronous driver path to the MOSFET was done with very low resistance and parasitic inductance to minimize emission ...
