TPS54550PWPR Product Details

SWIFT, PowerPAD are trademarks of Texas Instruments.

Description

The TPS54550PWPR 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 TPS54550PWPR has an under-voltage-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 TPS54550PWPR 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.
