PRINCIPLES OF OPERATION AND TYPICAL CHARACTERISTICS (continued)
Figure 3. Output Drivers With Low Source Impedance
The low source impedance of the output drivers provides rapid charging of power FET input capacitance while
minimizing external components.
Figure 4. UC1525A Output Saturation Characteristics.
Figure 5. Conventional Push-Pull Bipolar Design
In conventional push-pull bipolar designs, forward base drive is controlled by R1–R3. Rapid turn-off times for the
power devices are achieved with speed-up capacitors C1 and C2.
