Note 1: Absolute maximum ratings indicate limits beyond which damage to the device may occur. Electrical specifications do not apply when operating the device
outside of its rated operating conditions.
Note 2: The maximum power dissipation must be derated at elevated temperatures and is dictated by Tjmax (maximum junction temperature), θJA (junction to
ambient thermal resistance), and TA (ambient temperature). The maximum allowable power dissipation at any temperature is Pdmax =(Tjmax -TA)/ θJA or the number
given in the Absolute Maximum Ratings, whichever is lower.
Note 3: The human body model is a 100 pF capacitor discharged through a 1.5 k
Ω resistor into each pin. For Pin 8 (SW) the ESD rating is 1.0 kV.
Note 4: VDD tied to Boot and EN pins. Frequency pin tied to VDD through 121K resistor. VDD_ST =VDD when startu-up occurs. VIN is VDD + D1 voltage (usually
10-50 mv at start-up)
Note 5: This is the current into the VDD pin.
Note 6: This is the total current into pins VDD, BOOT, SW and FREQ.
Note 7: When the EN pin is below VEN_LO, the regulator is shut down; when it is above VEN_HI, the regulator is operating.
