一,产品概述(General Description)

The JTMT101XCL series is a synchronous step-up micro DC/DC converter which integrates an inductor and a control IC
in one tiny package (2.5mm×2.0mm, H=1.0mm). A stable step-up power supply is configured using only two capacitors connected
externally. An internal coil simplifies the circuit and enables minimization of noise and other operational trouble due to the
circuit wiring. The JTMT101XCL series can be used in applications that start from a single alkaline or nickel-metal hydride battery
because the input voltage range is 0.9V ~ 5.5V. The output voltage can be set from 1.8V to 5.0V (±2.0%) in steps of 0.1V.
PFM control enables a low quiescent current, making these products ideal for portable devices that require high efficiency.
The JTMT101XCL features a load disconnect function to break continuity between the input and output at shutdown
(JTMT101XCLA),and a bypass mode function to maintain continuity between the input and output (JTMT101XCLC).
