Step-down (Buck) Regulators
IDT’s energy-efficient, synchronous step-down regulators for non-isolated applications provide up to 95% efficiency. The step-down regulators feature integrated driver and power FETs, capable of leveraging a wide input voltage range and supporting up to 12A of output current.
About Step-down Switching Regulators
A step-down, or buck, switching regulator takes an input voltage and efficiently converts it into a regulated lower voltage. Devices typically come with fixed or adjustable output voltages. A good buck regulator will provide high-efficiency and excellent transient response under all load conditions. Buck regulators will often provide special features to ensure protection of the IC during fault conditions, such as under-voltage lockout, thermal shutdown, soft-start, currently limiting, and short-circuit protection.
