The UBA2024 is a half-bridge IC and 550 V lamp controller. This device is equipped with 9 ohm switches that espouses standard CFL applications up to 15 W. The number of external components can be reduced to only 17 (compared to the 27 typically required by a discrete driver solution) with high level of integration, and the IC supports NXP’s […]

This is a circuit of L200 light controller. The output of this circuit is controlled by the surrounding environment’s brightness. If the brightness increases, the output voltage will increases as well. Here is the circuit : The R1 and photoresistor are connected in parallel. They are used as regulator. If we connect the the photoresistor in parallel with R2, we […]

We can use boost converter such as TPS61160/1 with a 40V rated integrated switch FET to drive up to 10 LEDs in series. We can use it to reduce output ripple, improve conversion efficiency, and allows for the use of small external component. The external sensor resistor Rset is set on the default white LED current with feedback voltage is […]

This is a high-brightness LED-driver circuit. To provide a constant-voltage output we usually use DC/DC regulators. But constant-current output is the one that is needed in LED application. To provide a constant-current output, we can use this circuit. Here is the schematic diagram of high-brightness LED-driver circuit : This circuit uses R1 to sense the LED current. The TPS40211 is […]
