1-1-2 Switching Mode Regulator ICs Application Note s Heat Dissipation and Reliability s Mounting Torque The reliability of an IC is highly dependent on its operating temperature. SI-8000E Please be sure to apply silicone grease to the IC and to mount it to the SI-8000JF heatsink with a proper mounting torque. SI-8000S 0.588 to 0.686[N•m] (6.0 to 7.0[kgf•cm]) Heatsink design should pay particular attention to ensuring sufficient heat SI-8000TFE dissipation capacity.

RM4Z (Axial Type,VRM=200V,Io=3.0A) or SPI-8000A Series RBV-402 (Bridge Type, VRM=200V,Io=4.0A) Thus, thermal design must consider the maximum power dissipation STA810M Series RM10Z (Axial Type,VRM=200V,Io=1.5A) PD(max), which varies by the conditions of use, and the maximum ambient RM4Z (Axial Type,VRM=200V,Io=3.0A) or STA820M Series temperature Ta(max). RBV-402 (Bridge Type, VRM=200V,Io=4.0A) To simplify thermal design, Ta-PD characteristic graphs are provided herein. SI-8000HFE Series RBV-1506 (Bridge Type, VRM=600V,Io=15A) Please observe the following steps for heatsink design: 1. 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 determine 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 capacity of a heatsink highly depends on how it is mounted. Thus, it is recommended to measure the heatsink and case temperature in the actual operating environment. Please refer to the Ta-PD characteristic graphs for respective product types. ICs 45

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 67

1-1-3 Multi-Output Type Regulator ICs Application Note s Heat Dissipation and Reliability s Mounting Torque The reliability of an IC is highly dependent on its operating temperature. STA800M Series (when mounted by using a spring) Please be sure to apply silicone grease to the IC and to mount it to the 0.588 to 0.784 [N•m] (6.0 to 8.0 [kgf•cm] heatsink with a proper mounting torque. Heatsink design should pay particular attention to ensuring sufficient heat dissipation capacity. s Recommended Silicone Grease In addition, please take into account the air convection in operation. • Shin-Etsu Chemical Co., Ltd.: G746 The reliability of discrete components such as capacitors and coils is • GE Toshiba Silicones Co., Ltd.: YG-6260 closely related to temperature. A high operating temperature may reduce • Dow Corning Toray Silicone Co., Ltd.: SC102 the service life. Exceeding the allowable temperature may burn the coils or Please select proper silicone grease carefully since the oil in some grease damage capacitors. It is important to make sure that the temperature of products may penetrate the device and result in an extremely short de- output smoothing coils and input/output capacitors do not exceed their vice life. allowable levels during operation. With an adequate derating for the coils, minimize heat emission as far as possible. (For discrete components, refer to the individual user manuals.) s Thermal Design The maximum junction temperature Tj(max) given in the Absolute Maximum Ratings is specific to each product type and must be strictly observed. Thus, thermal design must consider the maximum power dissipation PD(max), which varies by the conditions of use, and the maximum ambient temperature Ta(max). To simplify the thermal design, Ta-PD characteristic graphs are provided herein. Please observe the following steps for heatsink design: 1. 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 determine 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 capacity of a heatsink highly depends on how it is mounted. Thus, it is recommended to measure the heatsink or case temperature in the actual operating environment. Please refer to the Ta-PD characteristic graphs for respective product types. ICs 83

Soft start at power on can be performed with capacitors connected to these pins. The outputs can also be turned ON/OFF with these pins. The outputs are stopped by setting the voltages of these pins to VSSL or lower. SS-pin voltages can be changed with open-collector drive circuits of transistors. When using both the soft-start and ON/OFF functions together, the discharge currents from C4 and C5 flow into the ON/OFF control transistors respectively. Therefore, limit the currents securely to protect the transistors if C4 and C5 capacitances are large. The SS pins are pulled up to the power supply in the ICs, so applying the external voltages are prohibited. ICs 87

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 coils L1, L2 • 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 about 2.0A, take care concerning heat radiation from the choke coil caused by magnetic saturation due to overload or short-circuited load. • Use a closed-magnetic-path coil to prevent interference between the channels SWout1 and SWout2. Capacitors C1, C2, C3 • As large ripple currents flow through C1, C2 and C3, use hi
