TPS54350

illustrate

The TPS54350 is a medium output current synchronous buck PWM converter with integrated high-side MOSFETs and an optional low-side gate to drive external MOSFETs. Features include a high-performance voltage error amplifier that enables transient conditions and selects output filter inductors and capacitors for maximum flexibility. The TPS54350 has an undervoltage latching circuit that prevents start-up until the input voltage reaches 4.5 volts; Internal slow-start circuitry to limit inrush current, and a power good output indicates valid output conditions. The synchronization function is not configured as input or output to facilitate 180° out-of-phase synchronization.

The TPS54350 device is available in a thermally enhanced 16-pin TSSOP (public works) PowerPAD™ package.
