●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
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.
Calculation of the maximum internal power consumption of IC (PMAX)
PMAX=(VIN-VOUT)×IOMAX
Where : VIN=Input voltage
VOUT= Output voltage IOMAX: Maximum output current)

●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
To enable standby mode for all channels, set the STBY pin to 0.5 V or less, and for normal operation, to 1.1 V or more.
Setting STBY to a voltage between 0.5 and 1.1 V may cause malfunction and should be avoided. 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. If the IC is switched on again while this voltage is present,
overshoot may occur on the output. 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
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 sudden accidents, please avoid
applications to where the over current protection circuit operates continuously.
9) Thermal Shutdown
This IC has Thermal Shutdown Circuit (TSD Circuit). When the temperature of IC Chip is higher than 175℃, the output
is turned off by TSD Circuit. TSD Circuit is only designed for protecting IC from thermal over load. Therefore it is not
recommended that you design application where TSD will work in normal condition.
10) Actions under Strong light
A strong light like a halogen lamp may be caused malfunction. In our testing, fluorescence light and white LED causes
little effects for the IC, but infrared light causes strong effects on the IC. The IC should be shielded from light like
sunrays or halogen lamps.
11) Output capacitor
To prevent oscillation at output, it is recommended that the IC be operated at the stable region shown in Figure 94. It
operates at the capacitance of more than 0.47μF. As capacitance is larger, stability becomes more stable and
characteristic of output load fluctuation is also improved.
