Texas Instruments' TPS63000 helps extend battery life in smart phones, digital still cameras and other single-cell, Li-ion-powered devices by providing high-efficiency buck-boost power conversion.

This design example report discusses a 0.5 W non-isolated buck-boost converter using the LNK302P. This design operates in an input voltage ranging from 85 VAC to 265 VAC and delivers an output of 0.5 ...

Electronic circuit designs often require power sources with negative output voltages. There are many different ways of producing a negative output voltage from a positive input voltage. One option is ...

Housed in an ultra-small package, a unique topology merges a switched capacitor and two-phase buck converter that can accept a 12V input and supply 1.2V output at 10A. 1. Converter circuit is 157 mm3 ...

In the last installment of Circuit VR, we walked around a simplified buck converter. The main simplification was using a constant PWM signal. The result is that the output voltage is a fixed fraction ...
