Output Ripple & Noise
Output Load Transient Response
Output voltage ripple at:
Tref = +25°C, VI = 53 V,
IO1 = 0.62 A, IO2 = 0.62 A resistive load.
Top trace: output voltage 1 (20 mV/div.).
Bottom trace: output voltage 2 (20 mV/div.).
Time scale: (1 s/div.).
Output voltage response to load current step-change,
output 1 (0.155-0.465-0.155 A) at:
Tref =+25°C, VI = 53 V IO2 = 0.62 A.
Top trace: output voltage 2 (200 mV/div.).
Bottom trace: load current output 1(0.2 A/div.).
Time scale: (0.1 ms/div.).
Output Voltage Adjust (see operating information)
Passive adjust
The resistor value for an adjusted output voltage is calculated by using the following
equations:
To adjust the output voltage upwards, a resistor is connected between pins 8 and 17.
Pins 8 and 9 have to be shorted. The output voltage increases when the resistance
decreases. The resistance value is given by the equation:
Rou= 4.54 x (15.31 – Vo) / ( Vo - Voi) k
Ω
To adjust the output voltage downwards, a resistor is connected between pins 8 and
9. The output voltage decreases when the resistance increases. The resistance
value is given by the equation:
Rod= 10.0 x ( Voi – Vo) / (Vo – 7.51) k
Ω
Vo is the desired output voltage and Vi is the initial output voltage.
