Fan Speed Controller with Linear or PWM Mode

General Description The G762/G763 is a single chip solution for fan speed control. It can be directly connected to the fan and performs close-loop or open-loop control. And there are two modes, PWM and linear, to drive the fan. It determined the current fan speed based on the fan rotation pulses

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

DESCRIPTION The ST763A is a step-down switching regulator . It operates from 3.3V to 11V giving a fixed 3.3V output voltage, delivering up to 500mA. The mainly features are typical efficiency of 90, quiescent current of 0.6mA, and only 0.2µA in shut-down. ■ OUTPUT VOLTAGE 3.3V ■ SUPPLY VOLTAGE
