The AME5140 switching regulator is current-mode boost
converters operating at fixed frequency of 1.6 MHz.
The use of SOT-25/TSOT-25, DFN-8(3mmx3mmx
0.75mm) & MSOP-8 packages, made possible by the
minimal power loss of the internal 1.8A switch, and use
of small inductor and capacitors result in the industry's
highest power density. The 30V internal switch makes
these solutions perfect for boosting to voltages up to 30V.
These parts have a logic-level shutdown pin that can
be used to reduce quiescent current and extend battery
life. Protection is provided through cycle-by-cycle current
limiting and thermal shutdown. Internal compensation
simplifies and reduces component count.
