TPS54308DDCR General Description
The TPS54308 is a 4.5-V to 28-V input voltage range, 3-A synchronous buck converter. The device includes two integrated switching FETs, internal loop compensation, and 5-ms internal soft start to reduce component count.
By integrating the MOSFETs and employing the SOT-23 package, the TPS54308 achieves high power density and offers a small footprint on the PCB.
The TPS54308 operates in force continuous conduction mode (FCCM) during light load conditions. The switching frequency is maintained at an almost constant level over entire load range.
Cycle-by-cycle current limit in both high-side MOSFETs protects the converter in an overload condition and is enhanced by a low-side MOSFET freewheeling current limit, which prevents current runaway. Hiccup mode protection is triggered if the overcurrent condition has persisted for longer than the present time.
Features
- 4.5-V to 28-V wide input voltage range
- Integrated 85-mΩ and 40-mΩ MOSFETs for 3-A, continuous output current
- Low 2-µA shutdown, 300-µA quiescent current
- Internal 5-mS soft start
- Fixed 350-kHz switching frequency
- Peak current mode control
- Internal loop compensation
- Overcurrent protection for both MOSFETs with hiccup mode protection
- Overvoltage protection
- Thermal shutdown
- SOT-23 (6) package
- Create a custom design using the TPS54308 with the WEBENCH Power Designer
