Switching Regulators

Some of the key requirements of today's power management solutions include less power consumption under various load conditions, less space, high reliability and wide input voltage. These requirements are driving the need for highly efficient, wide VIN, low quiescent current (IQ) switching regulators for DC-DC conversion in a broad range of applications.

Intersil offers a wide range of high performance switching regulators that operate with both synchronous and non-synchronous internal switches (FETs). Buck regulators (step-down) and boost regulators (step-up) operate with input voltages as low as 1.8V and as high as 60V and will generate output voltages as low as 0.6V. 

The switching voltage regulators can switch with speeds as high as 4MHz, provide high efficiency up to 95% and also have light load efficiency modes. The versitility of these DC-DC converters allow configuration for buck, boost, flyback, inverting in isolated and non-isolated applications.
