Overview
NEW PRODUCT A Product Line of Diodes Incorporated AP3585A/B/C SINGLE PHASE SYNCHRONOUS BUCK PWM CONTROLLER Description Pin Assignments The AP3585A/B/C is a compact synchronous-rectified buck controller specifically designed to operate from 4.
5V to 13.
2V supply voltage and deliver high-quality output voltage as low as 0.
8V (AP3585A) or 0.
6V (AP3585B/C).
This SO-8EP device operates at fixed 300kHz/200kHz frequency and provides an optimal level of integration to reduce size and cost of the power supply.
This controller integrates internal MOSFET drivers that support 12V+12V bootstrapped voltage for high- efficiency power conversion.
The bootstrap diode is built-in to simplify the circuit design and minimize external part count.
This controller provides single feedback loop, voltage-mode control with fast transient response.
The error amplifier features a 10MHz gain-bandwidth product and 6V/μs slew rate which enables high converter bandwidth for fast transient performance.
Other features include internal soft-start, under voltage protection, over current protection and shutdown function.
With afore mentioned functions, this part provides customers a compact, high efficiency, well-protected and cost-effective solution.
The AP3585A/B/C is available in SO-8 and SO-8EP packages.
