... IC internal element. LR BD8153EFV uses the current mode DC/DC converter control and has the optimized design at the coil value. A coil inductance (L) of 4.7 µ µH is recommended from viewpoints of electric power efficiency, response, and stability. (2) Output Capacity Settings For the capacitor to use for the output, select the capacitor which has the larger value in the ripple voltage V allowance value and the drop voltage allowance value at the time of sudden load change ...

... BD8153EFV (4) Setting the Phase Compensation Circuit the current mode control, since the coil current is controlled, a pole (phase lag) made by the CR filter composed of the output capacitor and load resistor will be created in the low frequency range, and a zero (phase lead) by the output capacitor and ESR of capacitor will be created in the high frequency range. In this case, to cancel the pole of the power amplifier easy to compensate by adding the zero point with C the illustration ...

... BD8153EFV (5) Regulator Controller Settings The IC incorporates a 3.3-V regulator controller, and a regulator can be formed by using an external PNP transistor. Design the current capability of the regulator with a margin according to the following formula. IOMAX = 7mA hfe [A] The hfe is the current gain of the external PNP transistor. ...

... BD8153EFV (7) Design of the Feedback Resistor Constant Refer to the following equation to set the feedback resistor. As the setting range, 10 k to 330 k is recommended. If the resistor is set lower than a 10 k, it causes the reduction of power efficiency set more than 330 k, the offset voltage becomes larger by the input bias current 0.4 µ ...

... BD8153EFV ●Gate Shading Setting Method The IG input signal allows the high-level and low-level control of the positive-side gate voltage. The slope of output can be set by the external RC. The recommended resistance set value is 200 to 5.1 k and the recommended capacitor set value is 0.001 µF to 0.1 µF. The aggravation of efficiency may be caused if settings outside this range are made. ...

... BD8153EFV ●Application Examples *Although we are confident that the application circuit diagram reflects the best possible recommendations, be sure to verify circuit characteristics for your particular application. When a circuit is used modifying the externally connected circuit constant, be sure to decide allowing sufficient margins considering the dispersion of values by external parts as well as our IC including not only the static but also the transient characteristic. ...

... BD8153EFV ●Operation Notes 1) Absolute maximum ratings Use of the IC in excess of absolute maximum ratings such as the applied voltage or operating temperature range may result in IC damage. Assumptions should not be made regarding the state of the IC (short mode or open mode) when such damage is suffered. A physical safety measure such as a fuse should be implemented when use of the special mode where the absolute maximum ratings may be exceeded is anticipated ...

... BD8153EFV 10) Thermal shutdown circuit This IC incorporates a built-in thermal shutdown circuit for the protection from thermal destruction. The IC should be used within the specified power dissipation range. However, in the event that the IC continues to be operated in excess of its power dissipation limits, the attendant rise in the chip's temperature Tj will trigger the thermal shutdown circuit to turn off all output power elements ...
