TPS54010PWPR

The Texas Instruments TPS54010PWPR is a high-performance synchronous buck PWM converter designed for low-input voltage applications requiring high output current. This integrated solution includes all active components necessary for a DC/DC regulator, simplifying design and reducing board space.

Key electrical specifications include an input voltage range of 2.2V to 4V and an adjustable output voltage down to 0.9V. It can deliver a maximum output current of 14A with a switch current limit typically at 21A. The device operates with a wide adjustable PWM frequency range from 280 kHz to 700 kHz, and features synchronous rectification for high efficiency. The quiescent current is typically 0.013A, with a maximum duty cycle of 90%.

Designed for robust operation, the TPS54010PWPR includes features like Enable, Frequency Synchronization, and Power Good indicators. It is externally compensated, allowing flexibility in output filter component selection. The operating temperature range is -40°C to 85°C. The integrated voltage error amplifier ensures maximum performance under transient conditions, and an undervoltage-lockout circuit prevents start-up until the VIN input voltage is sufficient.

Packaged in a 28-HTSSOP, this surface-mount device is suitable for applications where space and efficiency are critical. The 8-mΩ MOSFET switches contribute to high efficiency at 14A continuous output. The internal reference accuracy is 1%.
