Input Voltage Range

2.7V to 5.5V

Recommended Load Current

0A to 3.0A

−30°C to +125°C

−30°C to +90°C

(1)

All voltages are with respect to the potential at the GND pins. The LM3253 is designed for mobile phone applications where turn-on after

power-up is controlled by the system controller and where requirements for a small package size overrule increased die size for internal

Under Voltage Lock-Out (UVLO) circuitry. Thus, it should be kept in shutdown by holding the EN pin LOW until the input voltage

exceeds 2.7V.

(2)

In applications where high-power dissipation and/or poor package thermal resistance is present, the maximum ambient temperature may

part/package in the application (

cycle usage is assumed to drop (i.e., max power 12.5% usage is assumed) for 2G mode.
