AP3581B - Single Phase Synchronous Buck PWM Controller

Download the AP3581B datasheet PDF. This datasheet also covers the AP3581A variant, as both devices belong to the same single phase synchronous buck pwm controller family and are provided as variant models within a single manufacturer datasheet.

General Description

The1AP3581A/B/C1is1a1compact1synchronous-rect ified buck controller specifically designed to operate from 5V/12V supply and deliver high-quality output voltage as low as 0.6V (AP3581A) or 0.8V (AP3581B/C).

Key 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 solutions. The AP3581A/B/C is available in PSOP-8 package. Features.
  • Supply Voltage: 5V/12V.
  • VIN Input Range: 3.0V to 1.

OBSOLETE Data Sheet Single Phase Synchronous Buck PWM Controller AP3581A/B/C General Description The1AP3581A/B/C1is1a1compact1synchronous-rect ified buck controller specifically designed to operate from 5V/12V supply and deliver high-quality output voltage as low as 0.6V (AP3581A) or 0.8V (AP3581B/C). The AP3581A/B/C operates at fixed frequency of 300kHz (AP3581A/B) or 200kHz (AP3581C) 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 highefficiency power conversion. The bootstrap diode is built-in to simplify the circuit design and minimize external part count.
