Buck Controller from Diodes Incorporated Manages High POL Current

Diodes Incorporated (Nasdaq: DIOD), a leading global manufacturer and supplier of high-quality application specific standard products within the broad discrete, logic and analog semiconductor markets, today introduced a single-phase synchronous buck PWM controller series to meet the rigors of high-current desktop PC applications. Producing a continuous current of 25A, the AP3585 devices help simplify the design of distributed power architectures serving memory arrays and graphics processing units.

Offered in the compact and thermally efficient SO-8 and SO-8EP packages, the AP3585 series provides single feedback loop voltage-mode control, and operates from a supply of between 4.5V to 13.2V, delivering a high-quality output from as low as 0.6V up to 80% VIN.

The integration of a 10MHz error amplifier with a 6V/µs slew means the buck controllers exhibit a high converter bandwidth and a fast transient response. The devices have fixed oscillator frequencies of either 200kHz or 300kHz and feature a high level of integration, which helps to reduce the overall size and cost of power supplies.

With its built-in 12V+12V bootstrapped MOSFET driver and companion bootstrap diode, the AP3585 is able to achieve greater than 90% efficient power conversion while simplifying circuit design and minimizing the external part count.

The controllers feature comprehensive fault protection, consistent with their high-current operating capabilities, including lossless programmable overcurrent protection, under- and over-voltage protection, soft-start functionality and thermal shutdown.
