一,产品概述(General Description)

The JTMT210 series is a synchronous step-down micro DC/DC converter which integrates an inductor and a control IC in one
tiny package (2.0mm×2.5mm, h=1.0mm). An internal coil simplifies the circuit and enables minimization of noise and other
operational trouble due to the circuit wiring. A wide operating voltage range of 2.0V to 6.0V enables support for applications
that require an internally fixed output voltage from 1.0V to 4.0V in increments of 0.05V.
During stand-by, all circuits are shutdown to reduce currentconsumption to as low as 0.1μA or less.
With the built-in UVLO (Under Voltage Lock Out) function, the internal P-channel MOS driver transistor is forced OFF when
input voltage becomes UVLO ditect Voltage or lower.
The JTMT210 integrate CL discharge function which enables the electric charge at the output capacitor CL to be discharged via
the internal discharge switch located between the LX and VSS pins. When the devices enter stand-by mode, output voltage
quickly returns to the VSS level as a result of this function
