Notes:

• The use of negative voltages below − 0.3 V to the GND pin may create parasitic transistors on LSI lines, which can cause

abnormal operation.

• If LX terminal is short-circuited to VIN1 or VIN2 or GND line, there is a possibility to destroy it. Such usage is prohibit

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.
