FAN2013 — 2A Low-Voltage, Current-Mode Synchronous PWM Buck Regulator January 2008 FAN2013 — 2A Low-Voltage, Current-Mode Synchronous PWM Buck Regulator Features 95% Efficiency, Synchronous Operation Adjustable Output Voltage from 0.8V to VIN-1 4.5V to 5.5V Input Voltage Range Up to 2A Output Current Fixed-Frequency 1.3 MHz PWM Operation 100% Duty Cycle Low-Dropout Operation (LDO) Soft-Start Function Excellent Load Transient Response Power-Good Flag Over-Voltage, Under-Voltage Lockout, ShortCircuit, and Thermal Shutdown Protections 3x3mm 6-lead MLP Package Description The FAN2013 is a high-efficiency, low-noise, synchronous Pulse Width Modulated (PWM) currentmode DC-DC converter designed for low-voltage applications. It provides up to 2A continuous-load current from the 4.5V to 5.5V input. The output voltage is adjustable over a wide range by means of an external voltage divider. The FAN2013 is enabled when the input voltage on the VIN pin exceed the UVLO threshold. A current-mode control loop with a fast transient response ensures excellent line and load regulation. The fixed 1.3MHz switching frequency enables designers to choose a small, inexpensive external inductor and capacitor. Filtering can be accomplished with small components, reducing space and cost. Protection features include input under-voltage lockout, short-circuit protection, and thermal shutdown. Softstart limits inrush current during start-up conditions. The device is available in a 3x3mm 6-lea……
