PKM 1E PI Typical Characteristics
Output Ripple
Transient
Output voltage ripple (50mV/div.) at TPcb=+25 °C, Vin=53 V,
Io=15A resistive load with C=10 F tantalum and 0 .1 F
ceramic capacitors . Band width=20MHz . Time scale: 1s / div.
Output voltage response to load current step-change
(3 .75-11 .25-3 .37A) at TPcb=+25 °C, Vin=53 V. Top
trace: output voltage (50mV/div.) . Bottom trace:
load current (5 A/div.) Time scale: 0 .1 ms/div.
Output Voltage Adjust
Output voltage adjust resistor value vs .
percentage change in output voltage .
Output Voltage Adjust
The resistor value for an adjusted output voltage is
calculated by using the following equations:
Output Voltage Adjust Upwards, Increase:
Radj= 5 .11 [2 .5(100+Δ%) /1 .225Δ%- (100+2Δ%) /Δ%] kOhm
Output Voltage Adjust Downwards, Decrease:
Radj= 5 .11 [(100 /Δ%-2)] kOhm
Eg Increase 4% =>Vout = 2 .6 Vdc
5 .11 [2 .5(100+4)/(1 .225x4)-(100+2x4)/4]=133 kOhm
Eg Decrease 2% =>Vout = 2 .45 Vdc
5 .11 x(100/2-2)=245 .3 kOhm
Start-Up
Turn-Off
Start-up at Io=15A resistive load at TPcb=+25 °C,
Vin=53 V. Start enabled by connecting Vin . Top trace:
input voltage (10 V/div.) . Bottom trace: output voltage
(1 .0 V/div.) . Time scale: 5 ms/div.
Turn-off at Io=15A resistive load at TPcb=+25 °C,
Vin=53 V. Turn-off enabled by disconnecting Vin . Top
trace: output voltage (1 .0 V/div.) . Bottom trace: input
voltage (20 V/div.) . Time scale: 10 ms/div.
