DESCRIPTION/ORDERING INFORMATION

The TPS5435x is a medium-output-current synchronous buck PWM converter with an integrated high-side MOSFET and a gate driver for an optional low-side external MOSFET. Features include a high-performance voltage error amplifier that enables maximum performance under transient conditions. The TPS5435x has an undervoltage lockout (UVLO) circuit to prevent start-up until the input voltage reaches a preset value, an internal slow-start circuit to limit in-rush currents, and a power-good (PWRGD) 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 TPS5435x devices are available in a thermally enhanced 16-pin PowerPAD Thin Shrink Small-Outline Package (TSSOP). 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.
