PKM 1LE PI Typical Characteristics
Output Ripple
Transient
Output voltage ripple (5mV/div.) at TPcb=+25 °C, Vin=53 V,
Io=20A resistive load with C=10 F tantalum and 0 .1 F
ceramic capacitors . Band width=20MHz . Time scale: 2s / div.
Output voltage response to load current step-change
(5-15-5 A) at TPcb=+25 °C, Vin=53 V. Top trace:
load current (5 A/div.) . Bottom trace: output voltage
(100mV/div.) Time scale: 0 .1 ms/div.
Output Voltage Adjust (see operating information)
Start-Up
Turn-Off
Start-up at Io=20A resistive load at TPcb=+25 °C,
Vin=53 V. Start enabled by connecting Vin . Top trace:
input voltage (20 V/div.) . Bottom trace: output voltage
(0 .5 V/div.) . Time scale: 5 ms/div.
Turn-off at Io=20A resistive load at TPcb=+25 °C,
Vin=53 V. Turn-off enabled by disconnecting Vin . Top
trace: input voltage (20mV/div.) . Bottom trace: Output
voltage (0 .5 V/div.) . Time scale: 500 s/div.
The resistor value for an adjusted output voltage is
calculated by using the following equations:
Output Voltage Adjust Upwards, Increase:
Eg Increase 4% =>Vout = 1 .248 Vdc
8.85x(100+Δ%)x9.1x1.2
21.1x Δ%x1.225
- 5.11 kOhm
