Step-Down Converter
- GENERAL DESCRIPTION
The AS5430 is a monolithic synchronous buck regulator.
The device integrates 100mΩ MOSFETS that provide 3A continuous load current over a wide operating input voltage of 4.75V to 23V. Current mode control provides fast transient response and cycle-by-cycle current limit.
An adjustable soft-start prevents inrush current at turn-on. In shutdown mode, the supply current drops below 1uA. The device provides a very pact system solution with minimal reliance on external ponents.
