Since power dissipation changes substantially depending on the implementation conditions (board size, board thickness, metal wiring rate, number of layers and through holes, etc.), it is recommended to measure Pd on a set board. Exceeding the power dissipation of IC may lead to deterioration of the original IC performance, such as causing operation of the thermal shutdown circuit or reduction in current capability. Therefore, be sure to prepare sufficient margin within power dissipation for usage. Calculation of the maximum internal power consumption of IC (PMAX) PMAX=(VIN-VOUT)xIOUT(MAX.)

Absolute maximum ratings Use of the IC in excess of absolute maximum ratings (such as the input voltage or operating temperature range) may result in damage to the IC. Assumptions should not be made regarding the state of the IC (e.g., short mode or open mode) when such damage is suffered. If operational values are expected to exceed the maximum ratings for the device, consider adding protective circuitry (such as fuses) to eliminate the risk of damaging the IC. 2.) GND potential The potential of the GND pin must be the minimum potential in the system in all operating conditions. Never connect a potential lower than GND to any pin, even if only transiently. 3.) Thermal design Use a thermal design that allows for a sufficient margin for that package power dissipation rating (Pd) under actual operating conditions. 4.) Inter-pin shorts and mounting errors Use caution when orienting and positioning the IC for mounting on printed circuit boards. Improper mounting or shorts between pins may result in damage to the IC. 5.) Operation in strong electromagnetic fields Strong electromagnetic fields may cause the IC to malfunction. Caution should be exercised in applications where strong electromagnetic fields may be present. 6.) Common impedance Wiring traces should be as short and wide as possible to minimize common impedance. Bypass capacitors should be use to keep ripple to a minimum. 7.) Voltage of STBY pin To enable standby mode for all channels, set the STBY pin to 0.3 V or less, and for normal operation, to 1.2 V or more. STBY to a voltage between 0.3 and 1.2 V may cause malfunction and should be avoided. Setting Keep transition time between high and low (or vice versa) to a minimum. Additionally, if STBY is shorted to VIN, the IC will switch to standby mode and disable the output discharge circuit, causing a temporary voltage to remain on the output pin. occur on the output. If the IC is switched on again while this voltage is present, overshoot may Therefore, in applications where these pins are shorted, the output should always be completely discharged before turning the IC on. 8.) Over-current protection circuit (OCP) This IC features an integrated over-current and short-protection circuitry on the output to prevent destruction of the IC when the output is shorted. The OCP circuitry is designed only to protect the IC from irregular conditions (such as motor output shorts) and is not designed to be used as an active security device for the application. Therefore, applications should not be designed under the assumption that this circuitry will engage. 9.) Thermal shutdown circuit (TSD) This IC also features a thermal shutdown circuit that is designed to turn the output off when the junction temperature of the IC exceeds about 150. This feature is intended to protect the IC only in the event of thermal overload and is not designed to guarantee operation or act as an active security device for the application. Therefore, applications should not be designed under the assumption that this circuitry will engage. 10.) Input/output capacitor Capacitors must be connected between the input/output pins and GND for stable operation, and should be physically mounted as close to the IC pins as possible. The input capacitor helps to counteract increases in power supply impedance, and increases stability in applications with long or winding power supply traces. The output capacitance value is directly related to the Unstablevalue region overall stability and transient response of the regulator, and should be set to the largest possible for the application to increase these characteristics. During design, keep in mind that in general, ceramic capacitors have a wide range of tolerances, temperature coefficients and DC bias characteristics, and that their capacitance values tend to decrease over time. Confirm these details before choosing appropriate capacitors for your application.(Please refer the technical note, regarding ceramic capacitor of recommendation) Cout=0.47F, Cin=0.47F, Temp=+25 11.) About the equivalent series resistance (ESR) of a ceramic capacitor 100 Capacitors generally have ESR (equivalent series resistance) and it operates stably in the ESR-IOUT area shown on the right. 10 capacitors, etc. generally have different ESR, please check the ESR of the capacitor to be used and use it within the stability area range shown in the right graph for evaluation of the actual application.
