MP2104

1.7MHz, 600mA Synchronous

Step-Down Converter

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

main switch and

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

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.
