Figure 9: MGMT_PWR (3.3V) and BLUE_LED_PWR (5V)
output ripple/noise (2uS/div):
CH1: Vo, MGMT_PWR (20mV/div).
CH2: Vo, 5V BLUE_LED_PWR (20mV/div).
Test conditions:
(1) Feed A=48Vdc; Feed B=0Vdc
(2) I(3.3V)=1.25A,I(5V BLUE_LED_PWR)=0.1A
I(VRTN_OUT)=6.3A
(3) C2=220uF, C_hold=220uF
Figure 10: MGMT_PWR (3.3V) dynamic response
(1mS/div):
CH1: Vo, MGMT_PWR (50mV/div).
CH2: Io, MGMT_PWR (1A/div)
Test conditions:
(1) Feed A=48Vdc; Feed B=0Vdc
(2) 3.3V MGMT_PWR load current (50%-75%-50% of Io,max,
di/dt = 0.1A/µs), I(VRTN_OUT)=6.3A.
(3) C2=220uF, C_hold=220uF
