The buck-boost inductor must operate at a current level that is higher than the output load current. This is defined as I L = I/(1-D) or simply the input plus output current. For a negative output ...

2MHz, 95% efficiency, 12V, 4A buck-boost . The 2MHz, 12V, 4A buck-boost regulator in Figure 1 boasts efficiency to 95%. This relatively compact design uses 3mm × 3mm MOSFETs and a single high power ...

Combining a buck-boost topology and Silent Switcher technology brings very low EMI at the highest power-conversion efficiency. In many applications, voltages require upward and downward conversion ...

USB Type-C power products that use other lower-power sources—e.g., a 12-V wall adapter or a device with varying input sources—need both buck and boost dc-dc modes to produce the full 3.3- to ...

Kyoto and Santa Clara, Calif., Oct. 25, 2018 (GLOBE NEWSWIRE) -- ROHM today announced the availability of a buck-boost power supply chipset that provides the lowest current consumption in the ...

Buck-boost power supply IC achieves ultra-low current consumption (2.8μA)Combining low current circuit that provides ultra-low current consumption and fast response and an optimized switching ...

Aiming at automotive, Rohm has introduced a buck-boost dc-dc chipset, claimed to provide the lowest current consumption with good transient response for ECUs (electronic control units) for cluster ...

The op-amp used needs at least 20V supply, so it becomes quite useless for a power supply with less than 15V output. Plus, I don’t see any decoupling capacitors for the op-amp. Also, breadboard.

Buck-boost power supply IC achieves ultra-low current consumption (2.8µA) Combining low current circuit that provides ultra-low current consumption and fast response and an optimized switching control ...

Kyoto, Japan and Santa Clara, Calif., Aug. 27, 2019 (GLOBE NEWSWIRE) -- ROHM today announced the availability of a buck-boost DC/DC converter with integrated MOSFET, the BD83070GWL. It combines ...
