一,产品概述(General Description)

The JTMH8701 is hih efficiency, fixed frequency, Buck-Boost DC/DC converter that operates from input voltages above, below or equal to the output voltage. The devices are suitable for single lithium-ion, multicell alkaline or NiMH applications where the output voltage is within the battery voltage range.

The switching frequencies up to 1.5 MHz could be fixed by an external resistor. Also the oscillator could be synchronized to an external clock. The quiescent current is 1mA which maximizes the battery life in portable applications.

Other features include a 1µA shutdown, thermal shutdown and current limit. The JTMH8701 is available in the 10-pin thermally enhanced MSOP package (or upon request).
