一,产品概述(General Description)

The JTMA7079 is a compact, PFM mode, and step-up
DC-DC converter with low quiescent current. The inter-
nal synchronous rectifier reduces cost and PCB space
by eliminating the need for an external Schottky diode.
Low on-resistance of the internal switches improves the
efficiency up to 92%. The start-up voltage is guaranteed
below 1V. After start-up, the device can operate with input
voltage down to 0.7V. The JTMA7079 is suitable for por-
table battery-powered applications. Consuming only 11µA
quiescent current and an optimized control scheme al-
lows the device to operate at very high efficiency over the
entire load current range.
