Obtain the maximum ambient temperature Ta(max).2. Obtain the maximum power dissipation PD(max).3. Look for the intersection point on the Ta-PD characteristic graph and deter- mine the size of the heatsink.Although the heatsink size is now obtained, in actual applications, 10-to-20%derating factor is generally introduced. Moreover, the heat dissipation capacityof a heatsink highly depends on how it is mounted. Thus, it is recommended tomeasure the heatsink and case temperature in the actual operating environ-ment.Please refer to the Ta-PD characteristic graphs for respective product types. ICs 9

If other diodes like fast recovery diodes are used, IC may be destroyed because of the reverse voltage generated by the recovery voltage or ON voltage. Choke coil L1 • If the winding resistance of the choke coil is too high, the efficiency may drop below the rated value. • As the overcurrent protection starting current is approx. 2.5 A, take care concerning heat radiation from the choke coil caused by magnetic saturation due to overload or short-circuited load. Capacitor C1, C2 • As large ripple currents flow through C1 and C2, use high-frequency and low-impedance capacitors aiming for switching-mode-power-supply use. Especially when the impedance of C2 is high, the switching waveform may become abnormal at low temperatures. For C2, do not use a capacitor with an extremely low equivalent series resistance (ESR) such as an OS capacitor or a tantalum capacitor, which may cause an abnormal oscillation. Resistors R2, R3 • R2 and R3 are the resistors to set the output voltage. Set their values so that IREF becomes approx. 2 mA. Obtain R2 and R3 values by the following formula above. * To create the optimum operating conditions, place the components as close as possible to each other. ICs 61
