(2) This is a typical value only. The switching frequency will vary with input voltage. (3) The Inhibit control (pin 1) has an internal pull-up, and if left open-circuit the module will operate when input power is ap plied. A small low-leakage (<100nA) MOSFET is recommended to control this input. Ensure an On/Off transition time of ≤10µs. See application notes for more information. (4) The PT5520 Series requires a 100µF electrolytic or tantalum output capacitor for proper operation in all applications. (5) For operation below 0°C, the output capacitor C 2 must have stable characteristics. Use either a low ESR tantalum or Oscon® capacitor. (6) See SOA curves or consult factory for the appropriate derating. (7) The case pins on the through-hole package types (suffixes N & A) must be soldered. For more information see the applicable p ackage outline drawing.

Table 1 accordingly gives the allowable adjustment range for each model for either series as V a (min) and Va (max). Adjust Up: An increase in the output voltage is obtained by adding a resistor R2, between pin 5 (Vo adj) and pin 3 (GND). Adjust Down: Add a resistor (R1), between pin 5 (Vo adj) and pin 4 (Vout). Figure 1 The values of (R1) [adjust down], and R2 [adjust up], can also be calculated using the following formulas. Refer to Figure 1 and Table 2 for both the placement and value of the required resistor; either (R 1) or R2 as appropriate. (R1) = Ro (Va – 0.9) – Rs kΩ Vo – Va R2 = 0.9 Ro – Rs kΩ Va – Vo Where: V o = Original output voltage Va = Adjusted output voltage Ro = The resistance value from Table 1 Rs = The series resistance from Table 1 Table 1 ISR ADJUSTMENT RANGE AND FORMULA PARAMETERS

Place the resistor as close to the ISR as possible. 2. Never connect capacitors from Vo adj to either GND or Vout. Any capacitance added to the Vo adjust pin will affect the stability of the ISR. 3. For each model, adjustments to the output voltage may place additional limits on the minimum input voltage. The revised minimum input voltage must comply with the following requirement. V in(min) = (Va + 0.5)V or as specified in the data sheet, whichever is greater.
