一,产品概述(General Description)
The JTM6382 Series are synchronous PFM step-up DC-DC converters with very low
ripple noise due to the high operating frequency, and the maximum operating
frequency is 300KHz .
The output voltages of The JTM6382 Series can be programmable from 2.5V to 3.6V in
0.1V steps.
JTM6382 has high efficiency up to 95%. An enable pin (EN) is provided so that the
circuit can be powered down.
Only three components are required to realize the voltage step-up conversion
