TS1935
1.6MHz Boost Converter
with 30V Internal FET Switch
General Description
The TS1935 switching regulator is current –mode boost
converters operating at fixed frequency of 1.6MHz.
The use of SOT-25 made possible by the minimal power
loss of the internal 1.6A 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.
