一,产品概述(General Description)

The JTMT213/JTMT214 series is a synchronous step-down micro DC/DC converter which integrates an
inductor and a control IC in one tiny package (2.5mm×3.2mm, 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 2.7V to 5.5V enables support for applications that require an internally fixed output voltage (0.8V to 3.6V). The JTMT213/JTMT214 series uses synchronous rectification at an operating frequency of 3.0MHz. The JTMT213/JTMT214
series uses HiSAT-COT (*) synchronous rectification. HiSAT-COT+PWM control (JTMT213) or HiSAT-COT+automatic
PWM/PFM switching control (JTMT214) can be selected.The series have a high speed soft-start as fast as 0.3ms in
typical for quick turn-on. With the built-in UVLO (Under Voltage Lock Out) function, the internal P-channel driver
transistor is forced OFF when input voltage becomes 2.0V or lower. When CE=Low, the integrated 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. The power consumption will be less than 1.0μA.HiSAT-COT is an
original JIATAIMU term for High Speed Transient Response.
