■ NOTE ON USE
XC6190
Series
1. For temporary, transitional voltage drop or voltage rising phenomenon, the IC is liable to malfunction should the
ratings be exceeded.
2. Please use this IC within the specified operating ranges.
3. On the XC6190AN15xx and XC6190BN25xx, sufficiently reinforce the VIN – GND line, as power noise may cause
malfunctioning of the internal counter circuit. If necessary, connect a capacitor of at least 0.01μF between VIN-GND
near the IC.
On the XC6190AC15xx and XC6190BC25xx, connect a capacitor of at least 0.01μF between VIN-GND near the IC.
4. Connection of any component other than a resistor to the RT pin is prohibited on the XC6190Axxxxx-G. This may
cause malfunctioning.
Connect the external resistance (RT) between RT pin – GND near the IC.
5. When the mid voltage between “L” and “H” voltage is input into SW pin 1 and 2, the start-up and stop of the IC
malfunction. So please pay attention to the external components so that the mid voltage between “L” and “H” is not
input excessively and continuously to SW pin1 and 2.
6. When using for an application other than a push-button application, design the timing to include deviations and test
sufficiently with the actual device before use.
7. Torex places an importance on improving our products and their reliability.
We request that users incorporate fail-safe designs and post-aging protection treatment when using Torex products
in their systems.
