Description

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 under-voltage-lockout 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 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 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.
