3.3V, Step-Down, Current-Mode PWM DC-DC Converters

General Description The MAX748A/MAX763A are 3.3V-output CMOS, step down switching regulators. The MAX748A accepts inputs from 3.3V to 16V and delivers up to 500mA. The MAX763A accepts inputs between 3.3V and 11V and delivers up to 500mA. Typical efficiencies are 85 to 90. Quiescent supply current

NPN 2 GHz wideband transistor

DESCRIPTION NPN transistor in a plastic SOT54 (TO-92 variant) envelope. It is primarily intended for use in RF amplifiers and oscillators.

3.3V STEP DOWN CURRENT MODE PWM DC-DC CONVERTERS
