require DC - DC converters. It can be operated in a wide
input range from 3.0V to 40V and has the controlled duty
cycle oscillator, driver and high current output switch.
Also, With the internal temperature compensation circuit,
the AMC7660 provides an internally trimmed precision
1.5% reference voltage of 1.25V. These features make the
AMC7660
