GENERAL DESCRIPTION FEATURES

The   PT1203   is a monolithic pulse-width-modulated    2A Output Current
(PWM) synchronous step-down switch mode regulator          0.15? Internal Power MOSFET Switch
with a built in internal power MOSFET. It achieves 2A      Stable with Low ESR Output Ceramic
continuous   output current over a wide input supply Capacitors
range   with   excellent   load   and   line   regulation.   Current Up to 95% Efficiency
mode   operation provides fast transient response and 23μA Shutdown Current
eases   loop stabilization. Fault condition protection Fixed 350KHz Frequency
includes cycle-by-cycle current limiting and thermal Thermal Shutdown
shutdown. In shutdown mode, the regulator draws only       Cycle-by-Cycle Over Current Protection
23μA of supply current.                                    Wide 4.75V to 18V Operating Input Range
The   PT1203 requires a minimum   number of   readily Output Adjustable from 1.22V to 15V
available standard external components. The package is     Programmable Under Voltage Lockout
SOP-8.                                                     Available in 8-Pin SOP8 Packages
