DESCRIPTION
ATI2202 is a 340kHz fixed frequency PWM synchronous
step-down regulator. The ATI2202 is operated from 4.75V to
18V, the generated output is adjustable from 0.923V to
0.9VIN, and the output current can be up to 2A.
The integrated two MOSFET switches have a turn on
resistance of 0.13Ω. The current mode control provides fast
transient response and cycle-by-cycle over current protection.
The shutdown current is 1μA typical. Adjustable soft start
prevents inrush current at turn on. The ATI2202 features an
over temperature shutdown protection.
The ATI2202 is in a thermally enhanced SOP-8 package
which comes with a heat sink solder pad underneath, and it is
RoHS compliant and 100% lead (Pb) free.
