DESCRIPTION

The TPS54550 is a medium output current

synchronous buck PWM converter with an integrated

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

supply designs to meet aggressive equipment

development cycles.
