AP62xxx Synchronous Buck Converters

The AP62xxx family of DC/DC buck converters provides a robust set of features such as overcurrent protection, thermal shutdown, and synchronous rectification. These buck converters also offer high efficiency, cost effectiveness, design flexibility, and a wide range of other benefits all housed within compact and space saving designs.

Features and Benefits

•  Automatic Switching from PWM to PFM Mode (AP62150/200/200T)
  o  Maintains high efficiency, even during light loads (AP62201 maintains PWM operation at light loads)
•  Built-in Current Source on EN Pin
  o  Supports automatic start-up, UVLO threshold adjust, and sequencing
•  Internal 2.5ms Soft-Start Time
  o  Reduces start-up inrush currents
•  Constant On-Time (COT) Control
  o  Provides fast transient response and eases loop stabilization
•  Pin Compatibility Among 1.5A, 2A, 2.5A, and 3A Versions in SOT63 & TSOT26 Packages
  o  Allows for a simple PCB layout with design flexibility
•  4.2V to 18V Operating Voltage Range
  o  Works across the full 5V~12V range of appliance and consumer electronics applications
•  Selectable Switching Frequency: 400kHz/800kHz/1.2MHz
  o  Optimized converter which allows high-efficiency
•  Selectable Operation Modes: PFM/USM/PWM
  o  Pulse-frequency modulation – increases light load efficiency
  o  Ultrasonic mode – avoids audible frequency range
  o  Pulse width modulation – low output voltage ripple
•  Programmable Soft-Start and Tracking
  o  Reduced Inrush current and supports various tracking capabilities (ratiometric, coincidental, and sequencing)

Applications

•  5V and 12V Input Distributed Power Bus Supplies
•  Set-Top Box, IP Cameras, Gaming Consoles
•  Small-Cell Base Stations
•  Servers, Cloud Computing, Storage
•  Network Systems
•  Flat Screen TV Sets and Monitors
•  Home Appliances and Home Audio Systems
