A3. Revision notes - Practical Electricity
... This means the voltage across the variable resistor goes up (as the two resistors share the supply voltage). When the voltage across the variable resistor rises above 0.7 V, the NPN transistor switches ON and the LED comes on. By adjusting the variable resistor, we can adjust the temperature at whic ...

GS5802 - Globaltech Semiconductor
... The GS5802 uses a fixed frequency, peak current mode boost regulator architecture to regulate voltage at the feedback pin. The operation of the GS5802 can be understood by referring to the block diagram. At the start of each oscillator cycle the MOSFET is turned on through the control circuitry. To ...

Common Power Supply Topologies
... In the discontinuous state, there are three stages. 1. The transistor is on and the inductor current rises from zero to the peak current. The inductor stores energy during this stage (LI2/2) and the load is fed from the output capacitor. The diode isolates the load from the input. 2. As the transist ...
