Description

VCC

Logic and internal gate drive supply voltage. An internal zener clamp diode at 15.6 V nominal is

included to allow the VCC to be current fed directly from VIN typically by means of a high value

resistor.

Oscillator timing resistor input; a resistor is connected from RT to CT. RT is out of phase with

the half-bridge output (VO).

Oscillator timing capacitor output; a capacitor is connected from CT to COM in order to program

the oscillator frequency according to the following equation:

× (

) ×

Ω

where 75

Ω is the effective impedance of the RT output stage.

High side gate drive floating supply. For bootstrap operation a high voltage fast recovery diode is

needed to feed from VCC to VB.

VIN

High voltage supply.

Half-bridge output.

COM

Logic and low side of half-bridge return.
