Overview
Global Mixed-mode Technology AT1526 1MHz, All-Ceramic, 2A PWM Buck DC/DC Converter Features „ Ceramic Input and Output Capacitors „ Efficiency Up to 94% „ Guaranteed 2A Output Current „ Operate from 2.
5V to 6V Supply „ Adjustable Output from 0.
8V to VIN „ Internal Soft-Start „ Short-Circuit and Thermal-Overload Protection „ Input Over Voltage Protection „ RoHS Compliant Applications „ ASIC/DSP/µP/FPGA Core and I/O Voltages „ Set-Top Boxes „ Cellular Base Stations „ Networking and Telecommunications General Description The AT1526 high-efficiency, DC/DC buck converter delivers up to 2A of output current.
The device operates from an input voltage of 2.
5V to 6V and provides an output voltage from 0.
8V to VIN, making the AT1526 ideal for on-board post-regulation applications.
The AT1526 operate at a fixed frequency of 1MHz with an efficiency of up to 94%.
The high operating frequency minimizes the size of external components.
Internal soft-start control circuitry reduces inrush current.
Short-circuit and thermal-overload protections improve design reliability.
The AT1526 are available in a space-saving 8-pin SO package.
