and is not affected by the VB status. This ensures proper

charging of the bootstrap capacitor to bring the high side bias

supply VB above UVLO voltage.

Both the VCC and VB UVLO circuits are provided with

hysteresis feature. This hysteresis feature avoids errors due

to ground noise in the power supply. The hysteresis also

ensures continuous operation in case of a small drop in the

bias voltage. This drop in the bias can happen when device

starts switching MOSFET and the operating current of the

device increases. The UVLO feature of the device is

explained in the Figure 30.

OUTPUT STAGES

The NCP51530 is equipped with two independent drivers.

The output stage of NCP51530 has 1.7 A/2.2 A current

source/sink capability which can effectively charge and

discharge a 1 nF load in 15 ns.

The outputs of NCP51530 can be turned on at the same

time and there is no internal dead−time built between them.

This allows NCP51530 to be used in topologies like two

switch forward converter.

The figure below show the output stage structure and the

charging and discharging path of the external power

MOSFET. The bias supply VCC or VB supply the energy to

charge the gate capacitance Cgs of the low side or the top

side external MOSFETs respectively. When a logic high is

received from input stage, Qsource turns on and VCC/VB

starts charging Cgs through Rg. Once the Cgs is charged to

the drive voltage level the external power MOSFET turns on

the external MOSFET to discharge to GND/HB level.

When a logic low signal is received from the input stage,

Qsource turns off and Qsink turns on providing a path for

gate terminal of

As seen in the figure, there are parasitic inductances in

charging and discharging path of the Cgs. This can result in

a little dip in the bias voltages VCC/VB. If the VCC/VB drops

below UVLO the power supply can shut down the device.
