AN3203

AN3203 1MHz Step-Up PWM Converter with 2.5A Switch Current General Description Features The AN3203 is a current-mode boost DC/DC  Adjustable Output Voltage up to 18V converter with a 2.5A, 0.18Ω internal power  Internal 0.18Ω, 2.5A, 18V Power MOSFET MOSFET to provide this regulator highly power  Internal Soft-Start efficient. The AN3203 operates at 1MHz allowing  Fixed 1MHz Switching Frequency for easy filtering and low noise. Internal  Current Mode Operation compensation makes the user to set system easily,  Cycle-by-Cycle current limit which allows the use of small, low-ESR ceramic  Adjustable Over Current Protection output capacitors.  Input Under Voltage Lockout Fault protection includes over-current latch off,  Over-Temperature Protection input UVLO and thermal shutdown. This device  RoHS Compliant uses current mode control scheme that provides fast transient response. In shutdown mode, the Application supply current is less than 1u...
