Monolithic oscillator / power driver ZCC6501 Alternatively SN6501
I. Introduction:
ZCC6501 is a single oscillator / power driver, specifically isolate small size power application isolation interface for small form factor applications, isolated power supply. The driving device can be a thin intermediate from 3.3V or 5V direct current (DC) power supply transformer primary taps. The turns ratio of the transformer, the transformer secondary voltages may provide any isolation. ZCC6501 comprises an oscillator followed by a gate driver circuit, this circuit provides a compensated output signal to drive the N-channel power switch ground reference. This ensures that the internal logic circuit after the first opening and operation between the two switches. ZCC6501 a small small size transistors (SOT) -23 (5) package, and its rated operating temperature is between -40 ° C to 125 ° C.
Second, characteristics:
• push-pull drive for small transformers
• 3.3V or 5V single power supply
• high current driving the primary side:
O 5V Power: 350mA (maximum)
O 3.3V Power: 150 mA (maximum value)
• low rectified output ripple can use a small output capacitor
• small pin SOT-23 package 5
