Description

The FAN2011/FAN2012 is a high-efficiency, low-noise synchro-nous PWM current mode DC-DC converter, designed for low voltage applications. It provides up to 1.5A continuous load cur- rent from the 4.5V to 5.5V input. The output voltage is adjust- able 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 1µA.

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, inex- pensive external inductor and capacitor. Filtering is also easily accomplished with very small components.
