Introduction
The TPS54302 is a 3A synchronous buck converter with an input voltage range of 4.5V to 28V. The device integrates two switching FETs and features internal loop compensation and a 5ms internal soft-start to reduce component count. By integrating MOSFETs in a SOT-23 package, the TPS54302 achieves high power density with a minimal PCB footprint. Advanced Eco-mode is implemented to maximize light-load efficiency and reduce power loss. Spread-spectrum operation is incorporated in the TPS54302 to reduce EMI. Cycle-by-cycle current limiting on the high-side MOSFET protects the converter under overload conditions, with enhanced functionality provided by a low-side MOSFET freewheeling current limit that prevents current runaway. When the overcurrent duration exceeds a preset time, a hiccup-mode protection is triggered.
Features
- 4.5V to 28V wide input voltage range
- Integrated 85mΩ and 40mΩ MOSFETs with 3A continuous output current
- Shutdown current as low as 2μA, quiescent current of 45μA
- Internal 5ms soft-start
- 400kHz fixed switching frequency
- Spread spectrum for reduced EMI
- Advanced Eco-mode™ pulse skipping
- Peak current mode control
- Internal loop compensation
- Discontinuous mode overcurrent protection for both MOSFETs
- Overvoltage protection
- Thermal shutdown
- SOT-23 (6) package
Applications
- 12V and 24V distributed power bus supply
- Industrial applications
- White goods
- Consumer applications
- Audio
- Set-top box (STB), digital TV (DTV)
- Printers
