The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
The MP2104 is a 1.7MHz constant frequency,  
current mode, PWM step-down converter. The  
High Efficiency: Up to 95%  
1.7MHz Constant Switching Frequency  
600mA Available Load Current  
2.5V to 6V Input Voltage Range  
Output Voltage as Low as 0.6V  
100% Duty Cycle in Dropout  
Current Mode Control  
Short Circuit Protection  
Thermal Fault Protection  
<0.1µA Shutdown Current  
1.5V and 1.8V Fixed Output Versions  
Space Saving 5-Pin TSOT23 Package  
device integrates  
a
main switch and  
a
synchronous rectifier for high efficiency without an  
external Schottky diode. It is ideal for powering  
portable equipment that runs from a single cell  
Lithium-Ion (Li+) battery. The MP2104 can supply  
600mA of load current from a 2.5V to 6V input  
voltage. The output voltage for the MP2104DJ  
can be regulated as low as 0.6V, while the output  
voltages  
of  
the  
MP2104DJ-1.5  
and  
MP2104DJ-1.8 are fixed at 1.5V and 1.8V,  
respectively. The MP2104 can also run at 100%  
duty cycle for low dropout applications.  
APPLICATIONS  
The MP2104 is available in a low profile (1mm)  
5-pin, TSOT package.  
Cellular and Smart Phones  
Microprocessors and DSP Core Supplies  
PDAs  
MP3 Players  
Digital Still and Video Cameras  
Portable Instruments
