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 ...

Texas Instruments’ TPS53915 (Fig. 1), can supply up to 12 A output that is adjustable from 0.6 V to 5.5 V. Its input voltage ranges from 1.5 V to 18 V. A 4.5 V to 25 V VDD input powers an internal 5 V ...

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 ...

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 ...

STMicroelectronics has introduced a new family of ultra‑compact synchronous‑rectifier controllers designed to improve ...

(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 ...

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 ...
