Cyp9459 60V 500mA DC DC Step-Down Converter IC

General DescriptionThe 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.FeaturesOutput 0.5A peak current4.5V to 60 V operating input range1Ω internal power MOSFET480KHz fixed switching frequencyStable with Low-ESR Ceramic Output CapacitorsCycle-by-Cycle Over-Current ProtectionThermal shutdown protection>90% efficiencyOutput voltage: adjustable from +0.81V to 0.95VinLow shutdown mode current:
