Product Introduction
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.
