Note:

The output current from this device has a situation to decrease if the power supply voltage (VIN) and the DC/DC converter output

voltage (VOUT) differ only by a small amount. This is a result of slope compensation and will not damage this device.

WARNING:

The recommended operating conditions are required in order to ensure the normal operation of the semiconductor

device. All of the device's electrical characteristics are warranted when the device is operated within these ranges.

Always use semiconductor devices within their recommended operating condition ranges.

Operation outside these ranges may adversely affect reliability and could result in device failure.

No warranty is made with respect to uses, operating conditions, or combinations not represented on the data sheet.

Users considering application outside the listed conditions are advised to contact their representatives beforehand.
