1 / 10 page MP2104 1.7MHz, 600mA Synchronous Step-Down Converter MP2104 Rev. 1.3 www.MonolithicPower.com 1 10/4/2005 MPS Proprietary Information. Unauthorized Photocopy and Duplication Prohibited. © 2005 MPS. All Rights Reserved. The Future of Analog IC Technology TM TM DESCRIPTION The MP2104 is a 1.7MHz constant frequency, current mode, PWM step-down converter. The 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. The MP2104 is available in a low profile (1mm) 5-pin, TSOT package. ORDERING INFORMATION Part Number Output Voltage MP2104DJ-1.5 VOUT = 1.5V MP2104DJ-1.8 VOUT = 1.8V MP2104DJ VOUT = 0.6V to 6V EVALUATION BOARD REFERENCE Board Number Dimensions EV2104DJ-00A 2.0”X x 2.0”Y x 0.5”Z FEATURES • 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 APPLICATIONS • Cellular and Smart Phones • Microprocessors and DSP Core Supplies • PDAs • MP3 Players • Digital Still and Video Cameras • Portable Instruments “MPS” and “The Future of Analog IC Technology” are Trademarks of Monolithic Power Systems, Inc.
