TPS54353PWPR

The Texas Instruments TPS54353PWPR is a medium output current synchronous buck PWM converter. It integrates a high-side MOSFET and a gate driver for an optional low-side external MOSFET, offering high efficiency at 3A continuous output current.

Key electrical specifications include a 100 mΩ high-side MOSFET switch, a fixed 1.5V output voltage, and a wide PWM frequency range from 250 kHz to 700 kHz. The device also features internal compensation for a low parts count, synchronization to an external clock with 180° out-of-phase capability, internal slow start, and load protection via peak current limit and thermal shutdown.

Designed for applications such as industrial and commercial low power systems, LCD monitors and TVs, computer peripherals, and point-of-load regulation for high-performance processors, the TPS54353PWPR is available in a 16-pin TSSOP PowerPAD package. This surface-mount package is suitable for space-constrained designs.

The converter includes an under-voltage lockout circuit to prevent start-up until the input voltage reaches a preset value and a power good output to indicate valid output conditions. Its robust design ensures reliable operation in demanding environments.
