DC/DC converters help minimise external component count

DC/DC converters help minimise external component count
The MAX17242 MAX17243 step-down DC-DC converters from Maxim Integrated are now available at Mouser Electronics. These high-efficiency, synchronous converters with integrated MOSFETs help minimise external component count and reduce total cost of solutions for a variety of applications, including power regulation and general-purpose point-of-load.

Boost controller provides up to 97% efficiency

Boost controller provides up to 97% efficiency
Linear Technology has announced the LTC3897, a multi-phase synchronous boost DC/DC controller with input surge stopper and  diode controller. The boost controller drives two N-channel power MOSFET stages out-of-phase to reduce input and output capacitor requirements, enabling the use of smaller inductors versus the single-phase equivalent. Synchronous rectification increases efficiency, reduces power loss and eases thermal requirements.
