General Description
The FAN1538 provides two output voltages: a fixed 3.3V
ouput and either a fixed 2.5V or adjustable output with 1A
output current capability. Refer to Ordering Information for
details.
Current limit protects against short circuit currents and on
chip over temperature circuitry limits the maximum die tem-
perature.
Under voltage lockout and softstart circuitry protects against
unregulated output voltages when the input voltage is below
specification.
