The Texas Instruments TPS54357PWPR is a medium output current synchronous buck PWM converter. It features an integrated high-side MOSFET and a gate driver for an optional low-side external MOSFET. This device is designed for high efficiency at 3A continuous output current, with a 4.5A peak MOSFET switch capability.
Key electrical specifications include an input voltage range of 4.5V to 20V and a fixed output voltage of 5V. The switching frequency can be fixed at 250 kHz or 500 kHz, or adjusted from 250 kHz to 700 kHz. It also includes features like internal compensation, internal slow start, and adjustable undervoltage lockout.
The TPS54357PWPR 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 device is housed in a 16-pin TSSOP PowerPAD package, designed for surface mounting.
This converter provides load protection through peak current limit and thermal shutdown. It synchronizes to an external clock and offers 180° out-of-phase synchronization. The integrated high-performance voltage error amplifier ensures maximum performance under transient conditions.
