TPS54356PWP

The Texas Instruments TPS54356PWP is a synchronous buck PWM converter designed for medium output current applications. It features an integrated high-side MOSFET and a gate driver for an optional low-side external MOSFET, enabling high efficiency at 3A continuous output current.

Key electrical specifications include an input voltage range of 4.5V to 20V and a fixed output voltage of 3.3V. The device operates with a switching frequency of 250 kHz or 500 kHz, adjustable up to 700 kHz. It incorporates internal compensation for a low parts count and includes features like internal slow start, peak current limit, and thermal shutdown for load protection.

This converter is suitable for various applications, including industrial and commercial low power systems, LCD monitors and TVs, computer peripherals, and point-of-load regulation for high-performance DSPs, FPGAs, ASICs, and microprocessors. The TPS54356PWP is housed in a 16-pin TSSOP PowerPAD package, designed for surface mounting.

The device offers an adjustable undervoltage lockout and synchronizes to an external clock. It also provides a power good output to indicate valid output conditions. The 180° out-of-phase synchronization feature simplifies system design.
