s ABSOLUTE MAXIMUM RATINGS

* : The packages are mounted on the epoxy board (10 cm

× 10 cm).

WARNING: Semiconductor devices can be permanently damaged by application of stress (voltage, current,

temperature, etc.) in excess of absolute maximum ratings. Do not exceed these ratings.

s RECOMMENDED OPERATING CONDITIONS

* : See“ s SETTING THE TRIANGULAR OSCILLATION FREQUENCY”.

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

FUJITSU representatives beforehand.
