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 ...

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 ...

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 ...

(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 ...

When it comes to efficiency, every bit helps. Designers now are borrowing ideas from higher-power (200W and above) designs to squeeze every watt from low-power designs—50 to 200W. Consequently, the ...

PLANO, Texas--(BUSINESS WIRE)--Diodes Incorporated (Diodes) (Nasdaq: DIOD) has introduced a high-efficiency synchronous boost converter. The DIODES™ AP72250 is targeted at step-up conversion in ...

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 ...

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 ...

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 ...

TI's four-channel buck DC/DC converter with PMBus/I2C digital interface is well-suited for applications in space-constrained equipment that experience high ambient operating temperature without ...
