Buck-Boost LED Driver Using the PIC16F785 MCU
ثبت نشده
چکیده
• The on-chip op amp of the PIC16F785 is used to amplify the voltage across the current sensing resistor. This allows a much smaller sensing resistor to be used and reduces power dissipation. • The PIC16HV785 device can be used, which eliminates the requirement for an external 5V regulator when operating from higher supply voltages. • This application has unused analog resources which could be used to control another LED driver, power supply, or battery charging circuit.

Design of a Dual-input Buck-boost Converter for Mobile Back-lighting Applications
For mobile back-lighting applications, a dual-input white LED (WLED) driver using a bi-direction buck-boost converter is proposed in this paper. The proposed driver has two input terminals: battery input Vin1 and solar-cell input Vin2. Unlike conventional drivers using boost converters, step-up SC DC-DC converters, and so on, the proposed converter drives the anode and the cathode of LEDs by us...

The IDBB converter features just one controlled switch and two inductors and is able to supply a solid-state lamp from the mains providing high power factor and good efficiency. And with a careful design of the converter the filter capacitances can be made small enough so that film capacitors may be used. Thus the converter mean time between failures can be made as high as that of the solid-sta...
