High-efficiency Step-down DC/DC Converter

1.5A Low Voltage Current Mode Synchronous PWM Buck Regulator ,The FAN2011 FAN2012 is a high-efficiency, low-noise synchronous Pulse Width Modulated (PWM) current mode DC-DC Converter designed for low voltage applications. It provides up to 1.5A continuous load current from the 4.5V to 5.5V input. The output voltage is adjustable over a wide range of 0.8V to VIN by means of an external voltage divider.
The FAN2011 is always on, while the FAN2012 has an "Enable Input," and the device CAN be put in the shutdown mode, in which the ground current falls below 1A.
A current mode control loop with a fast transient response ensures excellent line and load regulation. The fixed 1.3MHz switching frequency enables the user to choose a small, inexpensive external inductor and capacitor. Filtering is also easily accomplished with very small components.
Protection features include input under-voltage lockout, short Circuit Protection and thermal shutdown. Soft-start limits in-rush current during start-up conditions.
The device is available in a 3x3mm 6-lead MLP package, making it possible to build a 1.5A complete DC/DC converter in a tiny space on the PCB.
