DESIGN FEATURESвЂ‰L Synchronous Boost Converters Provide
High Voltage without the Heat
by Greg Dittmer Introduction
The LTC3813 and LTC3814-5 reduce
the size of high voltage, high power
boost converters by incorporating
heat-saving features that eliminate
the need for large components and
heat sinks. In particular, two features
significantly reduce heat losses over
other high power boost solutions:
q Synchronous control eliminates
the high power loss in the diode
at high output currents
q Strong internal gate drivers
reduce switching losses at high
output voltages.
The LTC3813 can regulate output voltages up to 100V, while the LTC3814-5 is suitable for applications
up to 60V. They both use a constant
off-time peak current mode control
architecture. Current mode control
provides tight cycle-by-cycle monitoring of inductor current and constant
off-time allows high conversion ratios …
