The TPS5402 is a monolithic non-synchronous buck regulator with wide operating input
voltage range from 3.5 V to 28 V. Current mode control with internal slope compensation is
implemented to reduce component count.
TPS5402 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.
A cycle-by-cycle current limit with frequency fold back protects the IC at over loading
