Buck-boost converter topologies fit into a wide range of applications. Whether you are charging a battery from a battery, powering a string of LEDs, or running a handheld device from a single cell, ...

This DC-DC Bipolar PSU was developed for use with a guitar effects pedal. [Obsolete Technology] needed to source both positive and negative 15V. This is pretty easy to do if you’re converting… ...

Table 1 Summary of comparisons between non-isolated boost variations.. When designing the power stage of a double-boost, consider each step-up separately. In other words, when selecting components for ...

This schematic is all you need to build your own voltage converter. [Lutz] needed a converter that could boost 5 V to 30 V to power a string of LEDs. The solution was to use low cost ATtiny85 and s… ...

Fig. 1 shows the schematic of the boost converter. The circuit is built around a two-phase current-mode PWM controller (U1) with separate inputs for current limit and compensation for each channel.

DALLAS, Sept. 30, 2019 /PRNewswire/ -- Texas Instruments (TI) (Nasdaq: TXN) today introduced a family of four high-efficiency, low-quiescent-current (I Q) buck-boost converters that feature tiny ...

For boost converters such as white LED drivers that operate with such low output currents and high duty cycles, the switching losses are no longer trivial compared to the circuit's conduction losses.

DALLAS, Sept. 30, 2019 /PRNewswire/ -- Texas Instruments (TI) (Nasdaq: TXN) today introduced a family of four high-efficiency, low-quiescent-current (I(Q)) buck-boost converters that feature tiny ...
