Synchronous buck converters, as opposed to conventional buck converters, can achieve high efficiency in today's low-voltage, high-current applications because they replace the catch diode of buck ...

Lower operating voltages, increased current requirements, and the dynamic characteristics of formerly well-behaved µP loads place new demands on power distribution and management. To meet these ...

A high-efficiency, single-channel, synchronous-buck converter IC intended for point-of-load (POL) applications employs on-chip MOSFETs and proprietary mode control with adaptive on-time architecture.

(V3 is the input and V1, the IC power supply, would need to be made from the voltage across C4 – scroll down to see just the Cuk part) And a mini-obsession over the last few years has been trying to ...

Asynchronous vs. synchronous topologies. How a synchronous boost LED controller minimizes efficiency losses. The challenge of low-input-voltage operation. High-power LEDs continue to proliferate in ...

Linear Technology announces the LTC3520, a dual channel, 2MHz synchronous converter. One channel utilizes a synchronous buck-boost topology which can deliver up to 1A of continuous output current with ...

Vishay Intertechnology released two synchronous buck step-down controller ICs designed to operate with external MOSFETs in dc-to-dc converter circuits that require output currents upwards of 10 A. The ...

Texas Instruments (TI) introduced a four-channel buck DC/DC converter with PMBus/I2C digital interface for applications in space-constrained equipment that experience high ambient operating ...

Linear Technology has announced the LTC3335, a nanopower high-efficiency synchronous buck-boost converter with an onboard precision coulomb counter. It delivers up to 50mA of continuous output current ...

Linear Technology has announced the LTC3106, a highly integrated, 1.6µA quiescent current 300mV start-up buck-boost DC/DC converter with PowerPath management, optimised for multisource, low power ...

Diodes has announced the PAM2401 – a low voltage, 1MHz step up DC/DC converter designed to meet the heightened efficiency demands of portable products such as battery backups, cordless phones and GPS ...
