一,产品概述(General Description)
JTMA7178 is a 1.5MHz high efficiency monolithic synchronous buck regulator. Design with current mode scheme,the JTMA7178 is stable with
ceramic output capacitor. Input voltage from 2.7V to 6.0V makes the JTMA7178 ideally suited for single Li-Ion battery powered applications. 100%duty cycle provides low dropout operation, extending battery life in portable electrical devices. The internally fixed 1.5MHz operating frequency allows the using
of small surface mount inductors and capacitors. The synchronous switches included inside increase the efficiency and eliminate the need of an external Schottky diode.
The JTMA7178 is available in TDFN2x2-6 packages.
