The TPS54302DDCR is a 3-A synchronous buck converter with an input voltage range of 4.5 to 28 V. To reduce component count, the device contains two integrated switching FETs, internal loop correction, and a 5-ms internal soft start.
The TPS54302DDCR device provides great power density and a tiny footprint on the PCB by integrating MOSFETs and using the SOT-23 packaging. Advanced Eco-mode implementation increases light load efficiency while decreasing power loss. The frequency spread-spectrum operation is used in the TPS54302 gadget to reduce EMI. A cycle-by-cycle current limit in both high-side MOSFETs safeguards the converter in an overload condition, and this is supplemented by a freewheeling current limit in the low-side MOSFET, which prevents current runaway. If the overcurrent condition persists, hiccup mode protection is activated for longer than the present time.
