FAN2011/FAN2012 1.5A Low Voltage Current Mode Synchronous PWM Buck Regulator January 2005 FAN2011/FAN2012 1.5A Low Voltage Current Mode Synchronous PWM Buck Regulator Features Description ■ 95% Efficiency, Synchronous Operation The FAN2011/FAN2012 is a high-efficiency, low-noise synchro- nous PWM current mode DC-DC converter, designed for low ■ Adjustable Output Voltage from 0.8V to V IN voltage applications. It provides up to 1.5A continuous load cur- ■ 4.5V to 5.5V Input Voltage Range rent from the 4.5V to 5.5V input. The output voltage is adjust- ■ Up to 1.5A Output Current able over a wide range of 0.8V to V by means of an external IN ■ Fixed Frequency 1.3 MHz PWM Operation voltage divider. ■ 100% Duty Cycle Low Dropout Operation The FAN2011 is always on, while the FAN2012 has an “Enable ■ Soft Start Input,” and the device can be put in the shutdown mode, in ■ Excellent Load Transient Response which the ground current falls below 1µA. ■ 3x3mm 6-lead MLP Package A current mode control loop with a fast transient response ensures excellent line and load regulation. The fixed 1.3MHz Applications switching frequency enables the user to choose a small, inex- pensive external inductor and capacitor. Filtering is also easily ■ Hard Disk Drive accomplished with very small components. ■ Set Top Box Protection features include input under-voltage lockout, short ■ Point of Load Power circuit protection and thermal shutdown. Soft-start limits in-rush ■ Notebook Computers current during start-up conditions. ■ Communications Equipment The device is available in a 3x3mm 6-lead MLP package, mak- ing it possible to build a 1.5A complete DC/DC converter in a tiny space on the PCB.
