BOOT, VDD, EN and FB Pins

−0.5V to 10V

FREQ Pin

100µA

TJmax

(3)

150°C

Storage Temperature Range

−65°C to +150°C

Lead Temp. (Soldering, 5 sec)

ESD Rating (4)

2kV

(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.

(2)

If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and

specifications.

(3)

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.

(4)

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.

OPERATING CONDITIONS

(1)

VDD Pin

3V to 5V

FB, EN Pins

0 to VDD

BOOT Pin

0 to 10V

Ambient Temperature (TA)

−40°C to +85°C

(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.
