LX7175  
3V-5.5V, 3.5A Step Down  
PWM Switching Regulator  
Features  
. 3.5A Step-down Regulator  
Description  
. Operational Input Supply Voltage Range:  
LX7175 is a step-down PWM Switching Regulator  
IC with integrated high side P-CH and low side N-  
CH MOSFETs. The IC operates using a hysteretic  
3V-5.5V  
. Integrated PMOS and NMOS  
. Load Current from zero to 3.5A  
. 1.4MHz Switching Frequency  
control topology with  
a
full load switching  
frequency of 1.4MHz allowing small output filter  
components while maintaining excellent dynamic  
load response.  
. SKIP Pulse to Improve Light Load  
Efficiency  
The operational input voltage range of LX7175 is  
from 3V to 5.5V and it has two modes of operation  
selected externally by MODE pin. When MODE  
pin is high, it operates in continuous PWM  
operation and when it is tied low, it operates in  
Power Save Mode (PSM) with automatic transition  
between PWM and PSM mode depending on the  
load current. This allows the converter’s efficiency  
to remain high when load current drops.  
. Open VReg Type 0 LV Compatible  
. Input UVLO Protection  
. Enable Pin  
. Power Good  
. Internal Soft-start  
. Cycle-by-Cycle Over Current Protection  
. Latch Off Operation Under Output Short.  
. RoHS Compliant for Pb-free  
In the shutdown mode, the IC’s current consumption  
is reduced to less than 1µA and the output capacitor  
is discharged.  
Applications  
. Small Battery Operated Devices  
. HDD  
Other features of the part are: a) cycle-by-cycle  
current limit followed by latch off, b) thermal  
protection with hysteresis, c) internal digital soft  
start, d) and Power Good function.  
. Set-Top Box  
. LCD TV’s  
. Notebook/Netbook  
. Routers  
. Video Cards  
. PC Peripherals  
. PoE Powered Devices
