Product Description

General Description

The CYP9459 is a monolithic, step-down, switch-mode converter with a built-in power MOSFET. It achieves a 0.5A peak-output current over a wide input supply range with excellent load and line regulation. Current-mode operation provides a fast transient response and eases loop stabilization.
The wide input range (4.5V to 60V) provides high efficiency output of 0.5A current, Low shutdown mode quiescent current of 0.1μA is suitable for battery-powered applications.
Fault condition protections include cycle-by-cycle current limiting and thermal shutdown.
