onsemi FAN2001
the FAN2001/ FAN2002 is a high−efficiency, low−noise synchronous PWM current mode and Pulse Skip (Power Save) mode dc−dc converter. It can provide up to 1 A of output current over a wide input range from 2.5 V to 5.5 V. The output voltage can be externally adjusted over a wide range of 0.8 V to 5.5 V by means of an external voltage divider.| Part No. | FAN2001 |

DESCRIPTION
Designed for use in battery−powered applications, At moderate and light loads, pulse skipping modulation is used. Dynamic voltage positioning is applied, and the output voltage is shifted 0.8% above nominal value for increased headroom during load transients. At higher loads the system automatically switches over to current mode PWM control, operating at 1.3 MHz. A current mode control loop with fast transient response ensures excellent line and load regulation. To achieve high efficiency and ensure long battery life, the quiescent current is reduced to 25 mA in Power Save mode, and the supply current drops below 1 mA in shut−down mode. The FAN2001/FAN2002 is available in a 3x3 mm 6−lead MLP package.FEATURES
