Operation Description
The LM3200 is a simple, step-down DC-DC converter with a
bypass switch, optimized for powering RF power amplifiers
(PAs) in mobile phones, portable communicators, and similar
battery powered RF devices. It is designed to allow the RF
PA to operate at maximum efficiency over a wide range of
power levels from a single Li-Ion battery cell. It is based on
current-mode buck architecture, with synchronous rectifica-
tion for high efficiency. It is designed for a maximum load
capability of 300 mA in PWM mode and 500 mA in bypass
mode. Maximum load range may vary from this depending
on input voltage, output voltage and the inductor chosen.
The device has three-pin selectable operating modes re-
quired for powering RF PAs in mobile phones and other
