Tripath Technology, Inc. - Technical Information

caused by the output inductor LO during high output current conditions. An ultra fast

recovery diode that can sustain the entire VPP-VNN voltage should be used. In

most applications a 150V or greater diode must be used.

RSN

Output snubber resistor. This resistor forms a low pass filter with CSN with a

frequency of fC = 1/(2πRSNCSN). This RC filter removes any high frequency

overshoots that can be present on the switching output waveform. This RC filter

must be connected directly across the drain and source of the low side output

MOSFET.

CSN

Output snubber capacitor. This capacitor forms a low pass filter with RSN with a

frequency of fC = 1/(2πRSNCSN). This RC filter removes any high frequency

overshoots that can be present on the switching output waveform. This RC filter

must be connected directly across the drain and source of the low side output

MOSFET.

DG

Gate diode, placed in parallel to the gate resistor. This diode will help discharge the

parasitic capacitance at the MOSFET gates, thus decreasing the MOSFET fall time.

This helps reduce shoot through current between the top side and bottom side

output MOSFETs.
