4.5 To 20V Input, 6A Step Down Converter With Adjustable Output Voltage

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 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 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.
