high-side MOSFET and a gate driver for an low-side
external MOSFET. Features include a
high-performance voltage error amplifier that enables
maximum performance under transient conditions
and flexibility in choosing the output filter inductors
and capacitors. The TPS54550 has an undervoltage
lockout circuit to prevent start-up until the input
voltage reaches 4.5 V; a slow-start circuit to limit
in-rush currents; and a power good output to indicate
valid output conditions. The synchronization feature
is configurable as either an input or an output for
easy 180 ° out of phase synchronization.
The TPS54550 device is available in a
thermally-enhanced 16-pin TSSOP (PWP)
PowerPAD? package. TI provides evaluation
modules and the SWIFT? Designer software tool to
aid in quickly achieving high-performance power
APPLICATIONS
? Industrial and Commercial Low Power
Systems
? LCD Monitors and TVs
? Computer Peripherals
? Point of Load Regulation for
High-Performance DSPs, FPGAs, ASICs and
Microprocessors
