PMP15034 Test Results
Driving Voltage 10V/div
PWM 5V/div
Figure 6: Operating Waveform with 4-KHz PWM
The startup by EN waveform of the
±15-V circuit
is shown in Figure 7, the two output voltage ramps up to target
value within 7ms.
VOUT 5V/div
EN 2V/div
Double VOUT 10V/div
Figure 7: Startup at VIN=3.3V
Figure 8 shows the operating waveform with 4-KHz, 30% duty PWM input when VIN=3.3V. The rising and falling
time is very short because the totem pole has strong driving capability.
