Datasheet Summary
High-Efficiency Step-Down DC-DC Converter
1A
FAN2001/FAN2002
Description Designed for use in battery- powered applications, 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.
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...
