ABSOLUTE MAXIMUM RATINGS
These are stress ratings only and functional operation of
the device at these ratings or any other above those
indicated in the operation sections of the specifications
below is not implied. Exposure to absolute maximum
rating conditions for extended periods of time may affect
reliability.

ELECTRICAL SPECIFICATIONS
Specifications with standard type are for an Operating Junction Temperature of T J = T A = 25°C only; limits applying over the
full Operating Junction Temperature range are denoted by a “?”. Minimum and Maximum limits are guaranteed through test,
design, or statistical correlation. Typical values represent the most likely parametric norm at T J = T A = 25°C, and are
provided for reference purposes only. Unless otherwise indicated, V CC = 4.5V to 5.5V, V IN = 3.0V to 28V, BST = LX + 5V,
LX = GND = 0V, UVIN = 3V, CV CC = 1μF, C COMP = 0.1μF, C SS = 50nF, T A = – 40°C to 85°C, T J = – 40°C to 125°C.
