The Future of Analog IC Technology
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 low profile (1mm)
5-pin TSOT and 0.75mm TQFN-6 packages.

Notes:
1) Exceeding these ratings may damage the device.
2) The maximum allowable power dissipation is a function of the
maximum junction temperature TJ(MAX), the junction-to-
ambient thermal resistance θJA, and the ambient temperature
TA. The maximum allowable continuous power dissipation at
any ambient temperature is calculated by PD(MAX)=(TJ(MAX)-
TA)/ θJA. Exceeding the maximum allowable power
dissipation will cause excessive die temperature, and the
regulator will go into thermal shutdown. Internal thermal
shutdown circuitry protects the device from permanent
damage.
3) For recommended IR reflow temperature information, refer to
MPS document MP2104_IRRTP.
4) The device is not guaranteed to function outside of its
operating conditions.
5) Measured on JESD51-7, 4-layer PCB.
