ACE707A
Technology
Description
Micro Power Step-up DC-DC Converter
The ACE707A are Pulse Frequency Modulation (PFM) DC/DC converters. These two devices are
functionally equivalent except the switching current limit. The ACE707A is for lower power systems with
100mA current limit.
The ACE707A feature a wide input voltage. The operation voltage is ranged from 1V to 12V. A current
limited, fixed off-time control scheme conserves operating current, resulting in high efficiency over a broad
range of load current. They also feature low quiescent current, switching current limiting, low temperature
coefficient, etc.
Fewer tiny external components are required in the applications to save space and lower cost.
Furthermore, to ease its use in different systems, a disable terminal is designed to turn on or turn off the
chip.
The ACE707A are available in SOT-23-5 package.
