ACE7166X

1.2MHz, High Voltage, Boost Converter

VER 1.2

Description

The ACE7166X is a current mode step up converter intended for small, low power applications. The

converter input voltage ranging from 2.6V to 5.5V. The Output voltage can be set up to 27V. The

frequency is 1.2MHz allows the use of small external inductors and capacitors and provides fast transient

response. Internal soft start results in small inrush current and extends battery life. Internal power

to PFM during light load condition further increasing efficiency. The converter also provides protection

functions such as under-voltage lockout, current limit and thermal shutdown. The ACE7166X is available

in 5-pin TSOT-23 package.
