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 ...

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.

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 ...

(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 ...

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 ...
