AMS34063
GENERAL DESCRIPTION
The AMS34063 is a monolithic control
circuit containing the primary functions required
for DC/DC converters. The device consists of an
internal temperature compensated reference,
comparator, controlled duty cycle oscillator with
an active current limit circuit, driver and high
current output switch. This device is specifically
designed to be incorporated in step-down,
step-up and voltage-inverting applications with a
minimum number of external components. The
±2% internal reference and low quiescent current
of 1.6mA are among the improvements of the
device over the competition
