SNVS346H November 2007 – October 2024 LM3481
PRODUCTION DATA
The internal bias of the LM3481 comes from either the internal bias voltage generator or directly from the voltage at the VIN pin. At input voltages lower than 6 V the internal IC bias is the input voltage and at voltages above 6 V the internal bias voltage generator of the LM3481 provides the bias. The gate-driver supply voltage VCC requires an external bypass capacitor (0.47µF to 4.7µF depending on the FET requirements). Do not bias the VCC pin by an external voltage source.
