Description
- The TPS5403 is a monolithic non-synchronous buck regulator with wide operating input voltage range from 4.5 V to 28 V. Current mode control with internal slope compensation is implemented to reduce component count.
- TPS5403 also features a light load pulse skipping mode, which allows for a power loss reduction from the input power supply to the system at light loading.
- The switching frequency of the converters can be set from 50 kHz to 1.1 MHz with an external resistor. Frequency spread spectrum operation is introduced for EMI reduction.
- LX anti-ringing is added to address high frequency EMI issues.
- A cycle-by-cycle current limit with frequency fold back protects the IC at over loading condition.
