General Description:

The AX966 1is a monolithic, step-down, switch mode converter with a built-in power MOSFET. Capable of delivering up to 600mA of output current over a wide input supply range with excellent load and line regulation. At light loads, the regulator operates in low frequency to maintain high efficiency and low output ripple. The minimum input voltage may be as low as 4.5V and the maximum up to 55V, with even higher transient voltages. Fault condition protections include cycle-by-cycle current limiting and thermal shutdown.  The  AX966 1requires  a minimal  number  of readily-available external components. The AX9661 is available in a SOT23-6 package.
