AP3581A - Single Phase Synchronous Buck PWM Controller

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.
