Figure 1 shows a simple and efficient alternative topology. When the input voltage is lower than the output voltage, the circuit operates as a normal boost regulator. The inductor, L 1 , stores energy ...

You can reconfigure a buck regulator into a buck-boost circuit to convert a positive voltage into a negative voltage (Figure 2 ). The basic component configurations of both circuits are similar, and ...

A Buck, Boost, or Buck-Boost switching regulator topology usually consists of a diode, a switching element (MOSFET) and an energy storage device (inductor/capacitor) in the power path, and a ...

The LTC35361A synchronous buck-boost dc/dc converter provides up to 1 A at any voltage between 1.8 and 5.5 V from a single Li-Ion/Polymer battery, or 300 mA from a pair of alkaline ...

Semtech has announced the launch of the world's smallest 300mA buck boost regulator. The 3.3V, SC630A and 5V, SC632A are 300mA and 275mA (respectively) buck boost regulators in a 2 x 2 x 0.6mm package ...

Key Features of ISL9122A Buck-Boost Regulator with Bypass Ultra-low IQ <1.3 µA and low shutdown mode current of 7 nA to extend battery life ...

The ISL91127 and ISL91128 operate in buck, boost or buck-boost mod. The regulators’ input voltage, ranging from 1.8 to 5.5V, supports multiple battery topologies and their output voltage, ranging from ...

The LTM4605 integrates a synchronous buck-boost DC/DC controller, four N-channel MOSFETs, input and output bypass capacitors and the compensation circuitry in a 15mm x 15mm x 2.8mm land grid array ...

Intersil's ISL85403 is a 36 V, 2.5 A synchronous buck or boost buck controller with a high-side MOSFET and low-side driver integrated. In buckmode, the ISL85403 supports a wide input range of 3 V ...

Montreal, Canada (forpressrelease) August 26, 2020 - Future Electronics, a global leading distributor of electronic components, is featuring the Renesas ISL9122A Buck-Boost Regulator .

This is a switching regulator that supports buck, boost and inverting topologies, but perhaps it most notable feature is that it was first produced by Motorola in the early 1980s.
