This product requires two Schottky barrier diodes. We recommend the following components. Schottky barrier diodes: MA723 or equivalents Ta=25˚C Component Schottky barrier diodes Model number MA723 Typical characteristics Notes I F =200mA, VF ≤ 0.55V The MN3113F will not operate properly if the components do not satisfy the above specifications. Normal operation Faulty operation GND GND VL1/VL2 VL1/VL2 OVEE OVEE 0.7V or higher OFF Reversal OFF 2. Always use the specified components for peripheral circuits so as to ensure that OVEE and VL do not reverse potentials when the power is turned off. As the above sketch illustrates, allowing OVEE to exceed V L1 and VL2 by more than 0.7 V produces the risk of applying a forward bias to the PN junction, turning on the parasitic transistor, and generating an overcurrent that produces latch-up. If this phenomenon arises, increase the size of capacitor C8 or decrease the size of capacitor C10 to increase the OVEE time constant. (See the sample application circuit for the locations of C8 and C10.) MN3113F For Video Equipment 3. Adjusting boost voltages with SENSE pins The MN3113F provides the SENSE pins, SENSE1 and SENSE2, for adjusting the boost voltages (VOUT+ and VOUT– ) with the following procedures. Adjusting the positive boosted voltage (1) Making VOUT+ < 15V Insert a resistor, R, between the SENSE1 pin (pin 17) and the VOUT+ pin (pin 16). The theoretical output voltage at the VOUT+ pin is then given by the following formula. VOUT+' = VCC x 50kΩ + 100kΩ//R 50kΩ (where 100 kΩ//R is the effective resistance of the 100 kΩ resistor and R connected in parallel.) For example, if R is 50 kΩ, 50kΩ + 33.3kΩ VOUT+' = 5 x 50kΩ = 8.3V (2) Making VOUT+ > 15V Insert a resistor, R, between the SENSE1 pin (pin 17) and the GND pin (pin 42). VOUT+' = VCC x 50kΩ//R + 100kΩ 50kΩ//R Adjusting the negative boosted voltage (1) Making VOUT– < –10V Insert a resistor, R, between the SENSE2 pin (pin 39) and the GND pin (pin 42). VOUT–' = VCC x 50kΩ//R + 50kΩ 50kΩ//R (2) Making VOUT– > –10V Insert a resistor, R, between the SENSE2 pin (pin 39) and the VOUT– pin (pin 40). VOUT–' = –VCC x 50kΩ + 50kΩ//R 50kΩ For example, if R is 50 kΩ, VOUT–' = –5 x 50kΩ + 25kΩ 50kΩ = –7.5V Note, however, that the above formulas are mere guidelines, that the internal resistances vary between samples, and that therefore each sample will have to be adjusted. Note also that booster circuit capacity and output load current impose limits on adjustments for boosting VOUT+ above 15V and VOUT– below –10V. (The maximum possible adjustments are 20V for VOUT+ and –15V for VOUT– .)
