- Thermal Design This product exposes a frame on the back side of the package for thermal efficiency improvement. Within this IC, the power consumption is decided by the dropo ut voltage condition, the load cu rrent and the circuit current. Refer to power dissipation curves illustrated in Figure 44, 45 when using the IC in an environment of Ta ≥ 25 °C. Even if the ambient temperature Ta is at 25 °C, depending on the input vo ltage and the load current, chip junction temperature can be very high. Consider the design to be Tj ≤ Tjmax = 150 ℃ in all possible operating temperature range. Should by any condition the maximum junction temperature Tjmax = 150 ℃ rating be exceeded by the temperature increase of the chip, it may result in deterioration of the properties of the chip. The thermal impedance in this specification is based on recommended PCB and measurement condition by JEDEC standard. Verify the application and allow sufficient margins in the thermal design by the following method is used to calculate the junction temperature Tj. Tj can be calculated by either of the two following methods. 1. The following method is used to calculate the junction temperature Tj. Tj = Ta + P C × θJA Tj : Junction Temperature Ta : Ambient Temperature PC : Power Consumption θJA : Thermal Impedance (Junction to Ambient) 2. The following method is also used to calculate the junction temperature Tj. Tj = TT + PC × ΨJT Tj : Junction Temperature TT : Top Center of Case’s (mold) Temperature PC : Power consumption ΨJT : Thermal Impedance (Junction to Top Center of Case) The following method is used to calculate the power consumption Pc (W). Pc = (VCC - VOUT) × IOUT + VCC × Icc PC : Power Consumption VCC : Input Voltage VOUT : Output Voltage IOUT : Load Current Icc : Circuit Current

- Operational Notes 1) Absolute Maximum Ratings Exceeding the absolute maximum rating for supply voltage, oper ating temperature or other parameters can result in damages to or destruction of the chip. In this event it also becomes impossi ble to determine the cause of the damage (e.g. short circuit, open circuit, etc.). T herefore, if any special mode is being c onsidered with values expected to exceed the absolute maximum ratings, implementing physical safety measures, such as adding fuses, should be considered. 2) The electrical characteristics given in this specification may be influenced by conditions such as temperature, supply voltage and external components. Transient characteristics should be sufficiently verified. 3) GND Electric Potential Keep the GND potential at t he lowest (minimum) level under any operati ng condition. Furthermore, ensure that, including the transient, none of the pin’s voltage is less than the GND voltage. 4) GND Wiring Pattern When both a small-signal GND and a high current GND are present, single-point grounding (at the set standard point) is recommended. This in order to separate the small-signal an d high current patterns and to ensure that voltage changes stemming from the wiring resistance and high current do not cause any voltage change in the small-signal GND. Similarly, care must be taken to avoid wiring pattern fluctuations in any connected external component GND. 5) CTL Do not make voltage level of chip enab le keep floating level, or in between VthH and VthL. Otherwise, the output voltage would be unstable or indefinite. 6) Inter-pin Shorting and Mounting Errors Ensure that when mounting the IC on the PCB the direction an d position are correct. Incorre ct mounting may result in damaging the IC. Also, shorts caused by dust entering between the output, i nput and the GND may result in damaging the IC. 7) Inspection Using the Set Board The IC needs to be discharged after each inspection process as, while using the set board for inspection, connecting a capacitor to a low-impedance pin may cause stress to the IC. As a protection from static electricity, ensure that the assembly setup is grounded and take sufficient caution with tr ansportation and storage. Also, make sure to turn off the power supply when connecting and disconnecting the inspection equipment. 8) Thermal Design The power dissipation under actual operating conditions should be taken into consideration and a sufficient margin should be allowed for in the thermal design. On the revers e side of the package this product has an exposed heat pad for improving the heat dissipation. Use both the front and reverse side of t he PCB to increase the heat dissipation pattern as far as possible. The amount of heat generated depends on the voltage difference across the input and output, load current, and bias current. Therefore, when actually usi ng the chip, ensure that the generated heat does not exceed the Pd rating. Should by any condition the maximum junction temperature Tjmax = 150 ℃ rating be exceeded by the temperature increase of the chip, it may result in deterioration of the properties of the chip. The thermal impedance in this specification is based on recommended PCB and measurement condition by JE DEC standard. Verify the application and allow sufficient margins in the thermal design. 9) Overcurrent Protection Circuit This IC incorporates an integrated overcu rrent protection circuit that is acti vated when the load is shorted. This protection circuit is effective in preventing damage due to sudden and unexpected incidents. However, the IC should not be used in applications characterized by continuous operation or transitioning of the protection circuit. 10) Thermal Shut Down (TSD) This IC incorporates and integrated thermal shutdown circuit to prevent heat damage to the IC. Normal operation should be within the power dissipation rating, if however the rating is exceeded for a continued period, the junction temperature (Tj) will rise and the TSD circuit will be activated and turn a ll output pins OFF. After the Tj falls below the TSD threshold the circuits are automatically restored to normal operation. Note that the TSD circuit operates in a situation that exceeds the absolute ma ximum ratings and therefore, under no circumstances, should the TSD circuit be used in a set design or for any purpose other than protecting the IC from heat damage.
