MP1543  
1.5A, 500KHz Synchronous  
Rectified Step-up Converter

The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
The MP1543 is a highly efficient, synchronous,  
fixed frequency, current-mode step-up converter  
with output to input disconnect, inrush current  
limiting and internal soft-start. It includes an error  
amplifier, ramp generator, comparator, N-Channel  
switch and P-Channel synchronous rectified  
switch (which greatly improves efficiency). The  
output disconnect feature allows the output to be  
completely isolated from the input in shutdown  
mode.  
Over 90% Efficiency  
Output to Input Disconnect at Shutdown Mode  
Internal Synchronous Rectifier  
Inrush Current Limiting and Internal Soft-Start  
Internal Compensation  
1.5A Typical Switch Current Limit  
500KHz Fixed Switching Frequency  
Zero Current Shutdown Mode  
Thermal Shutdown  
5-Pin TSOT-23 Package  
The 500KHz switching frequency allows for  
APPLICATIONS  
smaller external components producing  
a
compact solution for a wide range of load  
currents. The internal compensation and soft-start  
minimizes the external component count and  
limits the inrush current during startup. The  
MP1543 regulates the output voltage up to 6V  
and provides up to 400mA from a 2-cell AA with  
a 3.3V output.
