●About input/output capacitor

Capacity value of ceramic capacitor - DC bias characteristics

(Example)

It is recommended that an input capacitor is placed near pins

between the VCC pin and GND as well as an output capacitor

between the output pin and GND. The input is valid when the

power supply impedance is high or when the PCB trace has

significant length. For the output capacitor, the greater the

capacitance, the more stable the output will be depending on

the load and line voltage variations. However, please check the

actual functionality of this capacitor by mounting it on a board

for the actual application. Ceramic capacitors usually have

different, thermal and equivalent series resistance

characteristics, and may degrade gradually over continued

use.

●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. Since

ceramic capacitors, tantalum capacitors, electrolytic 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.

●Power Dissipation (Pd)

As for power dissipation, an estimate of heat reduction characteristics and internal power consumption of IC are shown, so

please use these for reference. 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 the operation of the thermal shutdown circuit or reduction in current capability. Therefore, be sure to prepare

sufficient margin within power dissipation for usage.

●Operational Notes

1) Absolute maximum ratings

This product is produced with strict quality control, however it may be destroyed if operated beyond its absolute

maximum ratings. In addition, it is impossible to predict all destructive situations such as short-circuit modes, open

circuit modes, etc. Therefore, it is important to consider circuit protection measures, like adding a

fuse, in case the IC is operated in a special mode exceeding the absolute maximum ratings.

2) GND Potential

GND potential must be the lowest potential of all pins of the IC at all operating conditions. Ensure that no pins are at a

voltage below the ground pin at any time, even during transient condition.

3) Setting of Heat

Carry out the heat design that have adequate margin considering Pd of actual working states.

4) Pin Short and Mistake Fitting

When mounting the IC on the PCB, pay attention to the orientation of the IC. If there is mistake in the placement, the IC

may be burned up.

5) Actions in Strong Magnetic Field

Using the IC within a strong magnetic field may cause the IC to malfunction.

6) Mutual impedance

Use short and wide wiring tracks for the power supply and ground to keep the mutual impedance as small as

possible. Use a capacitor to keep ripple to a minimum.

7) STBY Pin Voltage

For standby mode, set STBY voltage below 0.3V. For normal operation, set the pin voltage beyond 1.5V. It is not

recommended to set STBY voltage between 0.3V and 1.5V, as it may cause malfunctions.

8) Over Current Protection Circuit

Over current and short circuit protection is built-in at the output, and IC destruction is prevented at the time of load

short circuit. These protection circuits are effective in the destructive prevention by the sudden accident. Please

avoid applications where the over current protection circuit operates continuously.

9) Thermal shutdown

This IC also features a thermal shutdown circuit that is designed to turn off the output when the junction temperature of

the IC exceeds about 170℃. 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 applications. Therefore, it is not recommended

that you design application where TSD will work in normal condition.

HYSTERESIS TEMPURATURE(℃) (typ.）

BHxxM0A series

10) Noise Pin

NOISE pin can drive small current, since it is directly connected to reference voltage circuit. The output voltage may

drop when the load of NOISE pin is more than 100nA. If the pin is connected to a capacitor, please use ceramic

capacitor for small leak current. Please take note that the output noise is smaller as NOISE pin capacitor is larger,

but startup time is longer.

11)Output capacitor

To prevent oscillation at output, it is recommended that the IC be operated at the stable region shown in Figure 12.

It operates at the capacitance value of more than 1.0μF. As capacitance is larger, stability becomes more stable and

characteristic of output load fluctuation is also improved.
