Diodes IncorporatedAP62600SJ-7DC to DC Converter and Switching Regulator Chip
Conv DC-DC 4.5V to 18V Synchronous Step Down Single-Out 0.6V to 7V 6A 12-Pin VQFN T/R
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
