The TPS54350 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 and flexibility in choosing the output filter inductors and capacitors. The TPS54350 has an under-voltage-lockout circuit to prevent start-up until the input voltage reaches 4.5 V; 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 TPS54350 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.

TPS54350EVM-235 — 具可調節輸出電壓、3A、4.5V 至 20Vin DC/DC 轉換器
The TPS54350EVM-235 evaluation module allows the designer to evaluate the TPS54350 SWIFT DC/DC converter optimized for small size and low height. The inductor and capacitors selected allow a wide 6-18V input and a 3.3V output up to 3A. The output voltage can be easily adjusted for lower DSP and (...)
