The SE8405 is a high voltage, non-synchronous step-down converter operates over a wide range input voltage 9V to 80V.
The SE8405 delivers 1.5A continuous load current with up to 95% efficiency. The SE8405 operates with fixed frequency peak current control with built-in compensation eliminates the need for external components.
Cycle-by-cycle current limit in high-side MOSFET protects the converter in an overload condition. Hiccup mode protection is triggered if the over-current condition has persisted for longer than the present time.
The SE8405 exhibits protection features that protect the load from faults like under-voltage, over-current and over-temperature.
The SE8405 is available in an ESOP-8 package.
